Base-Jungle is okay for the most part. Games can get a little grindy thanks to the energy removal cards and shit like Lickitung, Chansey, Mr Mime, Electabuzz, etc. Expect a lot of your turns to be attach an energy, maybe play energy removal, attack for 10 + status or pass, and hope for a good top deck next turn.
Rocket set fucked everything up with cards like Imposter Oak's Revenge and Rocket's Sneak Attack. Going first and playing those cards allowed you to fuck up your opponent's hand before their turn even begins. Combine that with Dark Vileplume to cuck your opponent out of trainer cards for the entire game.
Base-Gym is basically the same but now you have Erika's Jigglypuff winning on turn 1 with the right conditions.
Rocket-Neo is a little more fun. Evolution decks are better now thanks to Cleffa being the perfect early game setup mon. It's a little more luck based because of the babies and focus band forcing you into a lot of coin flips, but you have a lot more variety in decks now. Just make sure to play with Sneasel banned and the Slowking errata and you should have a good time.
Skip Expedition era, it's just three sets and overall forgettable.
