For flat bar or MTB type levers, I like the 1 or 2-finger type. I’ve had Tektro levers with sharper edges along the lever, but much prefer the levers with a more rounded cross section along the gripping length.
For drop bar levers, I’ve generally been happy with the brake levers themselves, but less happy when the hoods require me to bear weight between thumb and forefinger where nerves are. Something I may try is to ride the straight part of the drops mainly, turned up at least 15 degrees and bring the brake levers down so it’s almost like a pursuit bar brake setup. Kind of like an old vintage road bike.
My best compromise at the moment is a flat bar with Scott bar ends placed between the grips and brake levers and bar foam in the usual grip location, on the bar ends and between the brake levers and stem clamp. I use old stem shifters to leave more places on the bars for hands.
