We all have different preferences - threads like this always get long.
When I got the E-P2 and E-M5, I thought that the supplied straps were way too thin. The E-M1 one is quite sturdy, wide, has good grip, but as the OP says, definitely in your face.
At the time I got my E-P2, I chose the Domke Gripper straps with swivel connectors, but there and then in the UK I couldn't find them sold single so I reluctantly bought a pack of 6, two of black, sand and navy - after four years I think this was a good decision; I now have all my :43: and film cameras covered, with the same great straps.
The connectors rotate so there's no need to turn the strap or camera if the strap twists. The connectors are also detachable so you can disconnect the strap when switching to a sling or something... or you can change the colour of your strap if you have multiple
I bought the Peak Design Leash and I did like the connectors, but to me the strap looks and feels like a cheap ribbon key lanyard that I've seen tearing and breaking many times. Maybe I haven't spent enough time with it, but I don't think I'd trust it with my E-M1, never mind a (D)SLR. This is a biased opinion though so don't treat it too seriously.
