SharpCap 3.1 is much easier to use. I tried SGP but found it confusing and rather unintuitive. Sharpcap is free and there is a 10 pound annual fee to upgrade to Pro which I think gives sequencing control. I haven't bothered with that as the Ob is in the backyard and I just use Team Viewer to remote to the PC in the Ob from inside to control the software and guiding.
Give it a try, it's free so nothing to lose. Uninstall if you don't like it.

ZWO have their own lightweight version, ASICAP but it's a lot more limited.
