I prefer heroes 2 above the rest of the series, there is something magical about the balence between all of the factions and it doesn't feel like warcreaft fantasy vomit, but still remains bright and vibrant. but maybe that is nastalgia speaking. With the introduction of fheroes 2, there are a lot of QOL changes without changing the balence which is something that a lot of devs get wrong. highly reccomend.
I'll start off with the bad. -I don't like the updated models of any of the human cast, they are ugly and don't feel like they are intended to look human. luckily, you hardly ever see them. -Ryana never shuts up, you'll hear the same five or six lines about more enemies and kicking over beehives. it could be fixed by halving the number of cues and having more varied lines. other than that, it has a wide number of different chassis and each one has a different feel. even better, there are a number of mods that allow you to tweak just about any aspect of the game that you don't like or that you feel could be better. I reccomend it, mercs 4 did some things better. but again, you can tweak a lot with the current modding scene.
