When riding on clean, dry asphalt I use my front brake almost exclusively... water, sand or leaves on the road & the back brake comes into play some, snow & ice & I'll rarely use the brakes at all but if I do, it's the rear ofc - as a result I'd never even think of a dual pull on the winter beater bike lol
I've had a dual pull on my sunny summer cruiser & while I loved how it tidied up the bars a bit... I've never liked it's "numb" feel, never liked the feeling of uncertainty braking in a turn, never liked the unalterable 50/50 split - so after two years of "debating" with myself I tossed it for the more traditional two wheeler braking, dual levers for dual brakes.
The results? I shoulda done it from the start lol
Thing is, I'd not say dual pull brake levers are "bad" or even dangerous... but I would say they're overrated, as are the concerns of having a clutch & brake lever on the same bar overstated. I think it depends entirely on your choices - your riding conditions, habits & style.
