The main difference between the two is the "Clipping". The "scratchy and obnoxious" sound of the solid-state amp in clipping, compared with the much-more-mellow sound of the tube-amp clipping.
A second, more-subtle difference is that solid-state amps tend to have a fixed 50-percent duty cycle as they clip, whereas most class A tube amps clip with a duty cycle that varies as a function of the drive level.
Most of new solid-state amps include "amp modeling" technology. Modeling technology has come a long way in last couple of years and some of them are surprisingly almost 95-98% equal to a tube amp sound.
So in the end it comes to personal choice and your purchasing power. There are good and bad solid-state and tube amps available in the market. So its better to use your own preferences before buying any amp. " If you like it - Buy it! "
I would just write pros and cons of both solid-state and tube amps.
Pros: Warm tone, good harmonics, responsive ( compression, sustain, overdrive ) and more of "Fuzzy" sound.
Cons: Expensive to buy and maintain ( you need to replace tubes after some time ), Takes time to warm up, heavy-weight, more prone to failure during a gig.
Pros: Cheap, Reliable, Light-weight, normally brighter sound and easy to repair.
Cons: Bright tone is more harsh and aggressive ( example: Pantera sound )
Remember all tube amps are not great, and all solid-state amps are not crap. Play and check their sound before you buy. Its always safe to buy what you like then to buy what you don't.
