I have a dubious distinction of being around the 25 or 26 placed Grant (or did before I took a decently long break.) The M3 Lee/Grant is a medium that is tall, fat, slow and has the casemate gun of a TD. Oh, and you are right handed so you have to position yourself to have cover on the left side to allow your gun to work without too much exposure.
For all that, it is a dynamo at it's tier AS LONG AS YOU PLAY LIKE A TD and keep your head. The gun has really good pen for it's tier and the frontal armor, as others have said, is pretty good. It's side armor isn't all that bad, either, but you need to learn to angle a bit for better bounced hits against you. If you are top tier, don't get cocky, but be at the front as much as you can. At mid tier, you should be hanging back a bit and sniping like a TD, just closer than being called a Camper. At bottom tier, your best bet is to position yourself near other better units, but relatively safe from harm and peek and poke to make side shots or the occasional nice rear or sideskirt shot when they are busy with the bigger guys. Always be sure to make sure you're able to pop back under cover.
I am currently playing the Grant. I like playing them. Yes, they are challenging, which is the appeal for me.
The DW2 taught me not to hate my Churchill. The DW2 isn't as bad as most think, though. Bottom tier, you are more likely to be better off used as a doorstop, to be sure, but that doesn't mean you can't at least provide a deterrence effect by positioning yourself in a way that allows you to prevent your team mates ahead of you from being flanked. At bottom tier, you're a support unit and generally not a very good one.
That doesn't make you useless. Sometimes, the mere presence of another unit in the right spot can act as a wedge to prevent an opposing unit from an easy escape, which might make it easier for your team to take them out.
At your number of matches don't be in a hurry. Take your time and actually learn how to play. Sure, you can drive a tank, but so can a precocious four year old. Sure you can shoot and hit things. See that last but. The difference in good play and poor play is the idea in one's head that there is absolutely nothing you can do. A good player will not care that they are bottom tier and do their best to leverage their unit. This is the way you have to think if you wish to get better, no matter which unit you operate.
GL, HF & HSYBF!
