i have owned both, at the same time.
di+ and blowtorch are probably the most different two distortions you could ever compare
the di+ is a mid scooped distortion tone, whilst the blowtoch is more of a synthy fuzz than anything.
low drive sounds from the di+ are great, but the blowtorch sucks for low gain sound.
if you want great synthetic distortion, the blowtorch would be what you want.the mid range control on the blowtorch is brilliant, and the eq is very responsive.
basically we need to know what sound you want, as judging by you choosing these two pedals to compare, you either know nothing about the pedals or no idea what type of sound you are after
the ebs is analog, and the digitech is digital (i assume you mean the bass synth wah)
the bass synth wah does a great octave down, but you'll get a warmer more natural tone from the ebs, but of course you will get the usual analog tracking set backs.
