Maybe the War Thunder Tiger will be more Tiger-ey and fierce compared to the World of Tanks Tiger, which is a giant xp turkey for the enemy to riddle full of holes in it's tissue paper armour. The screenshots above certainly look nice.
Also, never ever start playing World of Tanks. Seriously, don't start. Do yourself a favour. It's ok-ish, but unless you're some kind of demi-god when it comes to controlling your own frustration levels, don't do it. Fire an awesome gun into the paper Hellcat front plate? - 'that one bounced!' What!?!? Encounter enemy T49 in your Stug - instantly get tracked by his first shot as he flies by you (always). At least they sort of cured your bullets coming sideways out your barrel in the 8.6 update now, one of my pet hates.
Some more WOT pain - not to be taken too seriously, but if you've played you may smile
Crazy grindfest
Horrible, horrible stock tanks, associated with the above
'They dinged us!' What? Didn't I just ding them?
Arty rain-o-doom.
Crazy fast scouts that fly all over the map, aka AMX ELC, Pz1C. Bastards.
World-o-Russian tank bias (hint - go for the KV1-Sport, grind the 122mm!)
Random number Trolling - catch fire at the worst time ever, crazy bounce mechanics, low/no hit damages
Odd sight behaviour, swinging gun up to the moon as you unzoom sometimes
Some very odd nerf/buff decisions
Until you get used to it, very strange visibility system (you don't 'see' what you actually 'see', you 'see' what the visibility system lets you 'see' to incorporate camoflage/nets etc)
And of course, totally random team mates who may be just as happy to drive off a cliff after accidentally teamkilling you as shoot the enemy!
I could go on and on even more
