It's not the steepnes per se, but steep and sustained that will get you. In Lofoten, the slabby nature means that you can rest almost anywhere, and with slab it's the angle of the rock, not the climbing (most of the lines in Lofoten still follow cracks, just like in Bohuslän).
And like I said, I have always found the grades to be more or less in line. Sure, some of the multipitch stuff might be a tad easier (not always), but single pitch vise they are about spot on.
That said, haven't climbed numerous 5s or 4s in Bohuslän (unlike in Lofoten), but 6s onwards it seems to hold true.
