Short answer, no.
Longer answer... my initial journey into buying the Land Cruiser I currently have started when my interest was piqued by rumors that the new 6th generation 4Runner would come with a hybrid option. After having owned only ICE vehicles for 30 years, I had told myself that my next vehicle purchase would be a hybrid, specifically a Toyota hybrid...they've been perfecting the technology for quite some time, and I trust Toyota for reliability. I liked the idea of adding their proven hybrid tech into larger vehicles like the Tacoma and 4Runner, not only for fuel economy benefits, but also for the improved performance it could potentially bring. Also, assuming the rumors about the new hybrid 4Runner were true, it would also fall right in line with my plan to purchase my next vehicle in 2026.
Well, as it turned out, I ended up buying a new vehicle about a year earlier than originally planned (don't need to tell that whole story here), but the Land Cruiser kinda swooped in and stole my attention from the new 4R... I preferred the styling of the LC, and once pricing was announced for the 6th gen 4R, and I knew I'd be paying comparable prices for the hybrid no matter which I choose, it was pretty easy for me to opt for the LC. (plus, while it wasn't a "must-have", I definitely prefer the full time 4WD of the LC over the RWD w/ part-time 4WD of most 4R models).
Many 4R reviewers who have done comparisons of both the hybrid and non-hybrid powertrains have noted the increase power of the former, and the fact that it's more enjoyable to drive. Sure, the actual impact on fuel economy of either doesn't seem too great, but for the increased HP and low-end torque alone, I'd opt for the hybrid every time.
If, instead of comparing the 4-cylinder iForceMax hybrid to the same engine in the iForce non-hybrid, we're comparing it to the twin-turbo V6 of the Lexus GX (for example), then I'm still opting for the hybrid of the LC, though this time primarily for fuel economy.
So no, no regrets here... I wanted a hybrid. I was interested in the Land Cruiser, in part, because it IS a hybrid. If the LC had only been offered with a different configuration without a hybrid, I would have probably waited for 6th gen hybrid 4Runner.
