I'd add the Blackheart Little Giant to the list as well.
I have the Epi and the Blackheart and I definitely prefer the Blackheart. The Epi is a bit dark and muddy for my tastes. Maybe if I had an EQ pedal to stick in front of it I would like it better. But as it stands, the Blackheart wins simply because it has a tone controls.
Got my Blackheart after I had the Jr and stopped using the Jr because the Blackheart is great. I play it all the time and it sounds great with the stock tubes. 3 or 5 watt switch too.
