As the only titles I've ever purchased/seriously-played for the past 2 gens are the RGG/Yakuza titles (and one-offs in 'mue 3 for PS4 and Binary Domain for PS3), I would have to compare the series on both gens.
Kenzan!
3
4
Dead Souls
5
Ishin!
0
Binary Domain
Those are a bunch of great titles, with the weakest being 4 and Dead Souls. The jump in graphic quality from Kenzan! to 0 was fairly marked and the gameplay did expand quite a bit, from being confined to two smaller locations (and a few one-off locations, in Kenzan! and 3), to multiple, larger locations, with umpteenth amounts of things to do. Binary Domain was a super title and you could see what RGG Studios was trying to do, with the voice command system (which I think would work without a hitch, on current-gen hardware).

'mue 3
Things expanded even more in terms of size, scope and things to do, gameplay-wise, with a sharp uptick in graphics and fidelity. YS Net got a lot out of the engine for what they were trying to accomplish and this seemed like more a of a, "polish," generation, than an experimental one, like with the PS3 titles.
For that reason, I would say I enjoyed this past gen, more than I did the previous gen, despite the previous gen having 2 of my 10 favourite Sega games of all time (3 and 5) and the latter gen only having 1 of my 10 favourite Sega games of all time (6). You could more-immerse yourself into this past gen, whereas the previous gen still saw a learning curve, in terms of innovation and breaking ground on what games were capable of and what the future held for development potential.
And 'mue 3 was just a wonderful experience, that maybe only Yakuza 3 could compare to, for me personally (about on-par with 5 and 6 or just a bit more-enjoyable than 5 and 6), which I don't think would have been fully-capable on PS3 (IMO, but I may be wrong).
So yes, in the end, I feel quite content with the titles from this past gen (8) and prefer it to the previous one (7).
