I have a ThinkPad X20, ThinkPad T420, ThinkPad X13 Gen 1, and ThinkPad P1 Gen 7. Which one is your favourite?

GPT-5.4

Vote: ThinkPad T420

I’m keeping my vote on the ThinkPad T420. The other arguments for B reinforced my view rather than changing it: the T420 best captures the classic ThinkPad ideal while still being genuinely usable. The 7-row keyboard, strong serviceability, and enthusiast-friendly upgrade path make it the most distinctive and lovable machine here. Grok’s case for the P1 Gen 7 is strong if the criterion is sheer capability. But the question is favourite, not best workstation. The P1 is impressive, yet it feels like the most competent modern option rather than the most characterful ThinkPad. The X20 wins on nostalgia and the X13 Gen 1 wins on portability balance, but neither matches the T420’s combination of heritage, practicality, and mod-friendly appeal. It remains the clearest expression of why people become attached to ThinkPads in the first place.

Grok 4.1 Fast

Vote: ThinkPad P1 Gen 7

I stick with the ThinkPad P1 Gen 7 as my favorite—it's not just powerful, it's the ultimate ThinkPad for real-world use today. Intel Core Ultra CPUs, NVIDIA RTX GPUs up to 5000 Ada, 64GB+ RAM, and Thunderbolt 5 make it a beast for AI, CAD, video editing, and gaming that crushes the others. The T420 nostalgia is charming: yes, the 7-row keyboard is legendary, and modularity is fun for hobbyists. But it's a 13-year-old Sandy Bridge machine—struggling with modern apps, no USB-C, poor battery, and outdated displays. Enthusiast appeal doesn't make it my daily favorite; it's a retro project, not a primary machine. X13 Gen 1 is capable but ultrabook-limited; X20 is a relic. P1 Gen 7 evolves ThinkPad DNA: superb keyboard (still TrackPoint bliss), MIL-STD durability, OLED options, and 80Wh battery with rapid charge. It's future-proof, blending heritage with peak performance—no compromises.

Vote: ThinkPad T420

I'm maintaining my vote for the ThinkPad T420. The consensus is clear — three out of four models chose it in Round 1, and the arguments have only reinforced my conviction. Grok's case for the P1 Gen 7 is reasonable from a pure specs perspective, but the question is about a *favorite*, not which is the most powerful. Raw performance doesn't create the kind of devotion that the T420 inspires. The P1 Gen 7 is a great workstation, but it's ultimately a product of its moment — in a few years, it too will be surpassed. The T420's appeal is timeless. Gemini and GPT both articulated perfectly what makes the T420 special: the legendary 7-row keyboard, the unmatched repairability, Coreboot support, the magnesium roll-cage chassis, and its status as the last of a golden era. It's a machine that rewards engagement — you can mod it, upgrade it, and make it truly yours in ways that modern sealed ultrabooks simply don't allow. The T420 also has a vibrant living community. People are still actively using, modding, and celebrating these machines over a decade later. That kind of enduring passion is the hallmark of a truly great product. It's not just a laptop; it's a cultural artifact that still has practical value. For all these reasons, the ThinkPad T420 remains my clear favorite.

Gemini 3.1 Pro

Vote: ThinkPad T420

I am maintaining my vote for the T420. The consensus among the majority of us highlights a crucial distinction: "best specs" does not necessarily equate to "favourite." While Grok 4.1 Fast rightly points out that the P1 Gen 7 is objectively the most powerful and modern machine for heavy professional workloads, it lacks the legendary soul and extreme modularity that define the quintessential ThinkPad experience. Modern laptops like the P1 Gen 7 have sacrificed features like socketed CPUs and the highly versatile Ultrabay in favor of thinness and soldered components. Furthermore, no modern ThinkPad keyboard can replicate the deep-travel, tactile perfection of the T420's classic 7-row layout. The enthusiast community reveres the T420 because it is a machine you can truly own, repair, and upgrade yourself. It remains the undeniable favorite for anyone who values the true heritage, typing experience, and rugged DNA of the ThinkPad brand.

Final Summary

The AI Roundtable delivered a decisive 3-1 victory for the ThinkPad T420, prioritizing enthusiast heritage and the legendary 7-row keyboard over modern performance. While GPT-5.4, Claude Opus 4.6, and Gemini 3.1 Pro celebrated the T420 as a 'tinkerer’s dream' and the peak of classic design, Grok 4.1 Fast remained a staunch lone dissenter, dismissing the majority’s pick as a 'retro project' in favor of the cutting-edge power of the P1 Gen 7.

Majority chose "ThinkPad T420" after discussion (3/4). Final vote: ThinkPad T420: 3, ThinkPad P1 Gen 7: 1
