SIP Trunk Provider recommendations? Both for reseller and use in my company

Hi! USA-based here. Crossposted from /r/voip as well

I currently sell Grandstream and 3CX PBX systems. I'm looking for SIP trunk providers that allow reselling, as well as a provider to use in my own company. (I figured I'd post both, since the the best option for each might not be the same). **Edit: Also possibly looking for something where the customer can pay on their own and I'll make commission; that makes my life easier.

I am looking at each of the ones on the 3CX recommended list (https://www.3cx.com/partners/sip-trunks/usa/), as well as voip.ms, and a few others. I figured I'd ask here and see what everyone's experiences were, since there weren't any recent topics on the matter!

Thanks

Edit: I decided to go with Telnyx, with Fractel as a possible backup. Telnyx has great pricing and features, and Fractel has great pricing and reseller/commission options.
