Mesh WiFi recommendations

Looking for a recommendation for a WiFi mesh system. Had orbi and finally quit, upgraded to a tplink deco from Costco. 3 satellites and it doesn’t seam as good as my old or I system. I’ve done many of the systems settings I found on here but still. It right. Seems slower and doesn’t have the same coverage as my old system. Any other recommendations for a different system.

2 story house plus basement. 3000 sq ft. I have a satellite unit on every level.
