Sorry if it's an oft asked (and answered) question but:

Tempted to replenish my screw stocks with one of the cases featuring in
Screwfix's clearout 'sale'.

Can someone enlighten me as to the differences in real terms - not in
the terms that appear in the Screwfix ads - between:

Turbo Ultra
TurboGold
Gold
Goldscrew Plus
Quicksilver

and then suggest which to buy (and why!)

I'm looking to buy the biggest offering in a case. I don't want
something requiring an esoteric driver and will only be doing what I
call crude timber fixing - no high class cabinet work, just a step up
from nailing bits of timber together or to walls and brackets to the
same (both interior and exterior).

TIA
