Hey, Imez,

The wheels - which are a bit looser, and that's why they can get noisy, can be made better rather easily, by putting rubber bands in the joints. These three models have it rather similar, with the Versatrax being a bit better off.

However, as a reversible pushchair, the Versatrax is better for smaller kids and will last less long (also will be bulkier). The Litetrax is a good basic model, while the Mytrax is a little sturdier and more all-terrain, but also a tad heavier.
