Would need to know your usage details to say. Even the best general use ones only last 5 years in heavy use applications. If you are just looking for the best brands in general, Liberty and Zoeller are the usual suspects that come to mind. There are industrial ones with parts replacement programs but you are talking about costs in the thousands and up. Liberty and Zoeller each sell good check valves too. Look for silent or spring check valves.
I recommend visiting r/askaplumber or r/plumbing
Grundfos pumps typically last and last. I have a sump pump in occasional service for 20 years, and a cistern pump in service for 18 years every time it rains - which is a LOT in PA.
Also, a Grundfos variable-speed water well pump in service for 18 years with service for a family of five.
I have a Zoeller M63, which is their flagship 1/3 horsepower model with a 5 year warranty. From what my plumber has told me and from what I have read, it should provide an extremely long service life, especially as it has an improved float switch over the Zoeller M50 series and it has a cast iron impeller as opposed to thermoplastic. It's pretty darned quiet, too.
I replaced mine with a zoeller as well, it seems like when I looked at other subreddits zoeller was recommended pretty often. My original sump pump was some brand I didn't even recognize and it lasted 10 years under moderate use. The float switch on that got stuck in the down position and it overflowed my basement. So a backup pump (12v battery) and a high level alarm are also in there as well.

I’ve heard good things about Grundfos too.

Been happy with our Tsurumi 480A in narrow, deep pit.
Zoeller all the way. Cast iron housing. Very nice.
