I think most have been said about the relation between NUT and MGE ;-)

Depending upon your exact power needs, and setup (single vs multi UPS,
rackmount, ...), you might prefer Pulsar Evolution or Pulsar EX RT. If you
need a bit more power and features / QOS, I would recommend the new Pulsar
MX.

You can get a bit of help to make your choice using the UPS Selector:

If you have more questions, don't hesitate to contact me back.
But as told, I'll be on holidays for 2 weeks as of tomorrow...
