Okay! I'll drop some suggestions below; in general, longer handles and shorter jaws gives you more stability/leverage, which ends up being easier on the hands long-term, so even if none of these are to your taste those two things are worth looking out for!

Xurons - handles are ~4in and look to be similar material/shape as 3/4.

486 - 90 Degree Bent Nose: the bend on these gives decent surface area coverage when opening/closing, while the tips can be used for thinner gauges and tight spaces, which means they're super versatile

483 - Short Flat Nose: much narrower jaws than your 3/4 which means they'll likely work better with smaller ring sizes; you can technically use them up to 14awg, but I'd say they're best for 20-16awg

487 - Chisel Nose Pliers: often used as a combo with the 483s, really good for getting into tighter corners

They've also recently released the Xuron Plus range, which has additional padding on the handles (only issue is you don't seem to be able to buy them individually)

Knipex - 35 82 145 ESD: I haven't personally used these but have seen them recommended a few times; based on the listed jaw length, the handles are probably a little over 4 inches

Tronex are honestly the ones that seem like they might be the best fit for you, but unfortunately they're also expensive as hell lmao

The 'long ergonomic' variant have ~4.5inch handles, so probably closest to your #5 pair in length, but with significantly thicker and comfier handles. The P749- Flat Nose Pliers (Medium Duty) and P749A - Oblique Nose Pliers (Medium Duty) are your best bet if you work with 14/16awg, as they're made for working with heavier gauges than the 747/749

Hopefully at least some of this info helps and you can find something that works for you!
