around 35 years ago I tried them both. X-Ring are easier, but some targets are too robust for them to puncture! If you get good enough you can hunt flies in the house with them. WARNING: Any female residents may forbid this in any dwelling they reside in, so you see there are pros and cons!

Speer is a more accurate system, and cuts cleaner holes in every target I tried. I preferred them.

Experiment: take sized and primed case, push into the slab of Gulf Wax paraffine. Makes a pretty good short range wadcutter. ANOTHER WARNING: Said females will expect you to clean all misses up right away, cause if you don't, there is a nasty mess. Cleanup may involve use of an electric iron to lift wax from the texture in the paint! (whatever you do, DO NOT USE SAID FEMALE'S CLOTHES IRON!!!
