I see this as complementary device to my big Switch. I plan on buying the rumored (but very likely) switch "pro that will be coming out mid-year. Some people ONLY play handheld, and if that is you - go for it.
Nintendo has fantastic customer service. So, I wouldn't worry about analog sticks too much since they will make free repairs within 1 year of purchase. I've only had one joy-con start drifting on me in my time as a switch owner (3 years?) The only concern with warranty repairs is that they might give you a replacement switch, which means you will lose your save data on some games like Pokémon, Minecreaft, or Splatoon 2, etc even if you ahve cloud backups.
At $140, odds are high that you will be able to take advantage of a GameStop trade-in promo to get your money back as well.
I personally got the 2-year replacement plan for $30 through GameStop, so if it "accidentally" dies just before 2 years is up - I can get a new one.
I would agree and I am an OG Switch gamer, that converted to a Switch Lite. It really depends on how you intend to play. From the sounds of it you may have benefited more from a traditional Switch because of some of the games that you like to play and the fact that you can put it on the TV. Games like Ring Fit are really tough on the Lite with the small screen AND you have to either own already or buy a set of joy-cons which completely kills the value of the system.
I only play in handheld mode, but that's the biggest appeal to me. It working the way it does is exactly why I was always so excited for the Switch since its announcement. I like the feel of durability the Lite brings and I have had a Switch since launch and never experienced Drift. It can happen of course but it really also depends how much time you are playing and the stress that you put on the sticks.
Just my two cents.
