Night and day difference between those 2 amps. I have both. Mod 50 has a totally different power section. Less headroom before your into the power section which means a warmer, fatter tone. Randall is more agressive sounding overall to me with less warmth and more sizzle. Egnater is smoother. Of course the Egnaters have some higher priced components and the sum of those parts does make a difference in sound and feel. The Randall is a great amp though and it really excells at the more aggressive tones.
