Code:
(visible slot, single bracer)
Ivy etched | Tigeraptor
AC 83 | 63
Str 7 | 28
Hp 30 | 15
Weight 26.1 | 14.6
I'm a massive fan of AC so if I had to pick one set it would be Ivy Etched, especially as that is the quintessential ranger armour for me (my ranger wore it for a long time).
…
BUT the str-weight of the tigeraptor is really tempting. Unlike ivy etched it actually increases your loot capacity (i.e. it works towards making it's cost back!)
Fashionwise I think Ivy Etched better advertises your class, and you seem to strongly weight fashion decisions so it may be worth doing that. IMHO Tigeraptor is a thing for bored 60s that already maxed tailoring might decide farm for an alt / to pass the time.
May I suggest an alternate armour?

A single bracer visible set gives 76 AC, 15 str and 25 hp (note the set lacks boots), only weighting 16.7, making it a decent compromise between the armours you are already considering. It also shares a graphic (though not necessarily tint), with kael and thurg quest armour, means you can plan a cohesive appearance for your characters progression.
