In Grim Dawn you play singleplayer locally and you can host your own server for up to 4-player multiplayer. In PoE you play on official servers with lots of options for multiplayer with friends or random people, people mostly play alone though.

I suggest watching some youtube videos of Necromancer builds in PoE and Ritualist(Necromancer+Shaman) builds in Grim Dawn, it's a solid choice like The Darkrayne mentioned. If you don't feel a need to min/max and push it to the limit, then a minion build can be pretty relaxing to play in PoE. Path of Exile is more fast paced and complex in general, if you are the type who likes to play your builds to maximum potential. They're both great games and both have interesting options for summoner/minion builds. Both Games are great, POE is free so you can give a shot if you want it.

Grim Dawn on other hand like i said have a easier learning curve and more like to be played alone, since you can find items for your build farming for yourself, and for both games minions builds are good and viable for endgame ( i liked grim dawn minion items and build interaction most). Hmmm, well, i've played path of exile for 2500 hours and grim dawn for 300hours and still going, grim dawn have a easier learning curve and poe, well, even with 200+ hours you'll still be a bit lost, both are pretty good games with a vast variety of spells and skills with their own mechanics, POE can be anoying sometimes with oneshot mechanics and you'll need to trade ALOT in order to get the items you want it, or be really really lucky dropping the items for your build (rarely), still POE have more build diversity, i don't really recommend it if you're going to play on slow pace, since most of the time you're going to learn about builds, items, spells mechanics and such.
