Just go with Stipe first
Had been with a couple previous hosts that I had problems with until a friend recommended to go with Stipe for Minecraft modpacks and I'm glad I switched.
Managing your server is easy, a wealth of documentation and tools are provided and support tickets for help with setting up modpacks, they also have a preset list for a wide variety of packs for express installation.
They say on their website they have an -average- response time of 15-20 minutes while I haven't specifically had that yet they still set and keep to a much higher bar for themselves than other hosts I've been with that would leave me hanging for 24 hours or more (with Stipe, one ticket was resolved late weekend evening on the 21st December within 2 hours), just really want to credit Stipe's *still* faster support here.
On top of that the servers were/are well performing for packs ive tried like Valhelsia 6, FTB Evolution, Craftoria, ATM9 and at an affordable rate to boot, thank you for helping us scratch the seasonal minecraft itch, will be sure to come back next round! :)
