There are 3 alternative options that I know ElectrumX, Electrs, and Fulcrum servers.
If you are looking for guides check the links below

Actually years ago I once tried ElectrumX before but my old laptop's pathetic hardware seems insufficient for it. Thus I turned to EPS then.
I may tried Electrs later. Thanks for your suggestion.
If you still care about performance or time to obtain transaction data, please read this benchmark first https://www.sparrowwallet.com/docs/server-performance.html. IMO Electrs and Fulctrum are best option, although each of them have different trade-off.
