In terms of ease of use, I find it's the logistics around the house that is a big factor. I've an old burley d'lite that's pretty wide (using with two sprogs) and makes getting it in and out the front door a right pain, but at the same time the alternative is a sloppy dark back lane access to a garage and simply getting in and out the garage door when there's nowhere to lean up is a ball ache.
If I were buying for one child, I think I'd go thule/chariot but would want to see if they easily fold flat and are easy to carry when folded as burley a pain. They just look sooooo slick/plush.
Also worth considering is storage space, whilst not a key consideration day to day, we got ours with touring in mind and burley wins all for space, loads of stash room. Would be good for cargo if the seats were ripped out.
I'd echo above comment re. Bike seat always being the preference but if you're doing 5 days a week then the winter throws up enough wet and cold to still get lots of use (warmer in trailer without wind chill and no dicking around with helmets or waterproofs either).
