I have 2 galaxies, 2 pyros and an exactor... and my fav depends on what type of work im doing,. each one is setup very differently. My 1 galaxie thats setup with 18g rear and 20g front is prolly my fav for black and grey, and my galaxie with 20g rear and 18g front is badass for color. both are very soft but each has a purpose in tuning. i tend to use my pyro cutback liner as a "workhorse" and very rarely use my conventional pyro liner, only when i need 2 specific liner setups or multiple session, big pieces. My exactor is a solid fill, tribalish only type of machine and unfortunately, sits in my drawer at the shop a bit too much. All in all, it really depends on how the machine is setup and what you're doing with it... but to answer your question, they're all my favorite.
