I'm a huge planet eclipse fan based on anytime I have had an issue it is always taken care of as if I'm the most important customer they have. It's a great feeling.
Ego is a poppit valve. Like stated 07 and up is pretty solid. I personally would go 09 and up for a few things that got redone.
Geo is a spool valve. The 2 is awesome. They can be found for very cheap used.
