Great lists! Most are somewhat similar, 3-4 supercars then a track car and a daily driver (usually a BMW). Many also stick a muscle car on there. Saw tons of unique cars like a Porsche914, etc.
For me it would really come down to what kind of money I had at the time. If I were really loaded I'd pick cars including a daily driver to match. Since I doubt I'll ever be that loaded I just don't know if I'd be that comfortable aggressively driving a $500k car.
My current garage is kind of weird and needs work:
1. FBO/modded 135 daily driver
2. 1994 Porsche 968 Cab part-time driver (original owner, 168k, needs paint, etc)
3. 1989 Toyota 4Runner (modded) (original owner, 145k, why paint it..lol)
4. 1977 Mercedes 450SEL 6.9 (had it since 1994, 68k, AMG cosmetic mods)
5. 1962 Mercedes 190SL, rusted out, took apart to restore in 1995
I should sell both my Mercedes first. 968's are great track cars but mine is a cabriolet so I'd really just as soon restore this one better and buy some other non-cabriolet for a track car.
Cars I have always loved that wouldn't be too hard to afford:
1. Acura NSX
2. BMW 850
3. mid 90's Porsche, would especially love a turbo and then mod it for more HP
4. Toyota Supra
If I were substantially better off financially I'd like to add:
1. Porsche Carrera GT or a Ford GT
2. Audi R8 or the new NSX if I had a little less money
