Hi there!
The Litetrax is a bit less roomy, perhaps, than other competing strollers on the market, partially so because of very nice padding making the seat slightly smaller. I wouldn't as it will last only till a child's 84 cm, but not for a 1-meter child either. For a normally-sized kid, it would last until approximately 2.5 to 3 years of age, from my experience. Each mother needs and wants something different, also in terms of the size, so it depends on your preferences and expectations, too.
About the closing, I don't think it is a con. I had strollers opening inwards and outwards, and those opening inwards often made dirty the canopy (by the wheels), while he outward-folding, you just shouldn't put on a dirty floor (but that you shouldn't even with those inwards folding, just saying :-D I see it as an advantage from the practicality of the folding mechanism, to be honest, the outward fold.
The pros of the Litetrax over Mytrax are definitely the weight, which is lower. The cons would be the less terrain-capable wheels that can rattle over bad bumps, the simpler hood, and no adjustable handlebar, which the Mytrax line features. Also, when using a carrycot/car seat, the Mytrax seat can be undressed completely, while the Litetrax's seat stays on.
Lastly, I think it is a nice urban model, comfy for the kid in terms of padding and shading, but yeah, it is not one of the largest, size-wise, and not the slightest eighter. I was considering getting it for my son at one point, but went of the Oyster Zero instead, as it was roomier and lighter (and I was very happy I did). But it definitely is a nice stroller, and if the price is right, it can work very nice for you.
