The 9th gen will be the best ;)
Think about it, your PS5/XBOII will be fully backward compatible with the current 8th gen games (they have to be since they will be running on the same x86-64 architecture). Online services would have fully matured by then and emulation for past consoles/streaming old games should be a piece of cake. Plus! You will finally be able to play in 1080P60 with 16xMSAA (imagine that!) while the PC snobs will be boasting about their 8K-capable rigs. Fun times ahead!
Personally, I like the 5th gen best since that's when the switch to 3D graphics occurred and I seriously got into gaming. Spent loads of time playing those PS1/Saturn games (and some time playing the N64 games when I borrowed the consoles from my friend).
I actually grew up with the 3rd playing Metal Gear on MSX and countless games on the NES but enjoyed the 4th more with all the variety of games and catchy music. I drastically reduced my gaming with the 7th gen so I don't have as many memories after that excpet with a few series like MGS and GT.
No foreign sky protected me,
No stranger's wing shielded my face.
I stand as witness to the common lot,
survivor of that time, that place.
