March makes amazing pumps. I worked for a tropical fish wholesaler and we pumped salt, fresh hot cold 24/7 for years. Mine died after 20+ years but I dropped it. It probably would.have gone 20 more. But it also was not made for brewing.
My chuggers have been going for years too though. Riptide has the bells and whistles. Has been made for brewing and has cool priming features. You can't really go wrong one of those 3. Blichmann stands behind his products though.
If I had a need for a new pump and cost was not an issue, I would get a riptide.
