If you are an experienced total war player and dont use strict house rules / roleplaying elements, then I suspect that you will find hard / medium very easy.

Personally I use VH/H. I find it challenging at times, but in general it is the most enjoyable level I have found. Very hard battles just frustrated me so much when your (infantry) elites get chewed up by levies - but that doesnt really ever seem to happen on Hard. Correctly deploying and organising your troops in a vaguely historical manner will allow you to win, you dont need to rely on gamey exploits like all FM armies or slinger / HA spam.

I use M/M so I don't have to deal with the diplomacy as much...it doesn't actually that much, but the AI does gleefully recruit mercenaries though.
Only difference I've seen is that the AI is SLIGHTLY less backstabbing and suicidal and the Eleutheroi don't attack you.

Practically the only reason I do not play on Very Hard campaign difficulty is because that is the only campaign difficulty in which I have noticed the rebels to actually besiege my towns. I don't mind being besieged, but I do mind VH campaign because of the fact that rebel armies can pop up out of absolutely nowhere, right next to a town, and conveniently besiege it. You can never see it coming. So this is why I used to play on H/M.

Now, the reason I started to play on H/H is because it gives the AI armies slightly more strength on the battlefield (oh, and I use Darth's formation mod, tailored for EB). This I only do because it gives me practice in defeating stronger armies, something players like me (of the weaker factions, such as Hayastan) need to increase in skill.

Micromanagement practice is one of my favorite events. All you have to do is give yourself a couple of house rules. For instance, give each unit orders individually. Eventually you'll get faster. Also, turn all skirmish modes and attack at will modes off. Increases your acuteness. Real great if you plan on playing strong players online.
