This is a commuter? With occasional longer weekend rides for recreation? You'd better lay out your very specific needs for the bike before considering this model and that. You'll be in a tail chase that will result in a bike that's unlikely to be ideal for your purposes.

1) Fenders/Mudguards - you'll be riding regularly in rain
2) Eyelet Mounts for Rear Rack - you want to wear a backpack in Summer? panniers are a better option.
3) Frame Clearance For Tires - in addition to the fenders, you'll want tires at 28mm minimum, more like 32mm
4) Upright or Relaxed Ride - so not a sport/racing type bike, but rather sport/touring, touring, cyclocross, etc.
5) Gearing - depending on your terrain, you'll at least want the gear range that you can use, particularly carrying a light load
6) Hand Position - do you want drop bars? could you use flat bars, or would you convert if the bike you found needed changing.

So, maybe none of the bikes you listed meet this set of needs. Are each in a size that can be adapted to fit you properly?

A rigid fork steel MTB is a great idea, but maybe a steel cyclocross bike or tourer would be a better starting point. Do you have someone close by who is mechanically adept with bikes, and/or has a stash of parts to make some simple swaps for you?
