I already own a suhr riot and a vox wha wha
Now i want to buy a flash back or a spark booster ftom tc electronics
which do you thing is more improtant?
They are two completely different pedals by the same company.

What do you want more, a delay or a boost pedal? Neither is more important, it depends on what you would use more.
I'm Mitch, I like making guitar and bass gear reviews/comparisons on YouTube

I play bass in an instrumental band called Beyond the Woods
I have a flashback and whilst it is a very nice pedal, probably so is the spark booster. The best one for you depends on what you want. Elaborate on your OP, TS

See, it's important that people clarify when they say "metal", because I pretty much always assume they are a Cannibal Corpse fanboi.
I'd suggest the Flashback. Chances are you can change channels on your amp with a footswitch anyway, if the amp you have is decent enough. I have a Flashback, and it really adds flavour to solos and guitar licks. Does your amp have built-in reverb though? That's just as important as delay.
I own a Marshall DSL40c and I use only the clean channel because I prefer the suhr 's distortion ...
