I have Adaptec AND LSI controllers running in the same machine. I've used HighPoint as well. No issues with any of them personally.
RAID Controllers, as a rule, are enterprise class hardware pieces used in datacenters for very serious applications. From what I understand, they are all very robust, regardless of manufacturer.
I can't comment about service, since I've never required it.
I will say however that Adaptec Controllers seem to run the HOTTEST out of the 3 brands mentioned. This is well supported on many forums where people have had to install after-market fans on the heatsink to keep it from overheating.
All RAID controller cards generate huge amounts of heat, and because they're rated to run in highly chilled server cabinets/data centers, it's not part of the spec to come with cooling fans.
I've only noticed anecdotally that LSI and HighPoint seem to run a tad cooler than Adaptec.
