I've only used
ElectrumX, it appears to be the most common server implementation. I've had it running for months without issue. Configuration options require a bit of research, but once it's set up it's pretty bullet proof. It requires a full node, unpruned, with
txindex turned on, so it'll require quite a bit of diskspace for the whole setup.
Cool, I have a full unpruned node with txindex so not a problem. Not super technical though so not sure if the configuration options will be a hurdle, I'll stick with the working setup for now while researching. Thanks again for the insight and help
