As promised I'm reporting back.
Received both of the suits yesterday.
I don't have a lot of suits to compare to except for the boxy Moores suit my dad gave me about 7 years ago.
I like the material. It's thinner than the Moores suit but feels good. A lot better than then crappy poly blend suits from Zara.
Fit is ALMOST perfect. Why almost? I blame my damned sloped shoulders.
Because of this the sleeves of the jacket falls about 0.5"-1" short.
Trousers needs to hemmed but otherwise the suit fits perfect. Nice slim fit but not overly like Zara suits. Zara suits fits very slim and the jackets are shorter. Very trendy but it won't last.
I've decided that I'll be keeping the Dark grey (Charcoal) one.
The Navy has the slightest shine to the material. It looks great no doubt but I think as my first nicer suits the Dark grey is more versatile for me. If I'm getting a 2nd suit I will go for the Navy one for sure.
This is just my initial impressions and I might get better pictures and report back.
Please excuse the quick and dirty pic (and dirty mirror) with non-matching tie

Oh and please chime in if you like to comment on the overall fit.
