Yeah, so if comfort is a high value, the Defender is not for you. However, it is far more affordable than a G-wagen, unless you're looking at an older G-wagen. Still, there's nothing like a Defender.
You have access to a much larger pool of Defenders than those of us across the pond. Over here, we have to rely on Defenders over 25 years old unless you have deep pockets for the few NAS trucks, which are limited to '94,'95 & '97 for '90s and '93 for 110s. From where I sit, I'd say get the newest Defender you can, but the danger is once you've had one, you'll most likely catch the fever.
In all seriousness, get out and explore. You can visit the US and still buy an older 4x4. And if you buy a LR, they've been making mechanics of owners since 1948...
