You'd better have a pretty big back yard for either of them.
Indoor is viable, but only with either a very large indoor venue, such as a school gym, or with a very small & stable chopper, such as the E-Sky Lama V3 (or "Co-Co Lama" as Hobby-Lobby) calls it. That one really can be flown indoors; I've got one.
Bring it outdoors, and it's useless though.
I think you're on the right track, though you might consider a sim instead. Get your skills up, and spend that money ahead of time on the sim instead of on parts. Once you get beyond the Honeybees and Lamas, that sim will pay for itself right quick.
Of course, FMS is a pretty good sim, and it's free, though the physics are not quite as good as the other ($200) sims. I remember every less-than-perfect landing on FMS registered as a crash. But it helped tremendously. Search on FMS and download it. Buy a quality dual analog USB game controller for your PC. Learn for $25. Crashes are free. The worse repair takes less than one second to make. Your fleet is huge. The weather is as good or bad as you want it. Flying venues are numerous and also free. The only bad thing is that you're just training. You're not flying. But that's all in your head. Put in the time to train, you will thank us later. The learning curve for helis is too steep to do any other way. You probably know this from your earlier experience.
Personally, I did my initial learning on FMS. Then I bought a Honeybee fixed-pitch, then a Lama, then a T-Rex (still in kit form waiting for more money) then a sim (AeroFly). I finally got a couple of dead-calm days in which to fly the Honeybee FP; it was glorious, but only because of my sim practice.
As you probably know, any collective pitch chopper will handle a little wind better than the fixed pitch jobs. But they also break easier on account of the extra mechanical complexity.
