Yes. ;D Which of the two are most in common with the Infantry.
Let me caveat this by saying that while I have been an infanteer and am currently a gunner, my knowledge of armoured capabilities only comes from working alongside the RCD's.
In an honest attempt to answer your question, the answer is both and neither. It really depends how you are employed, what you are doing and what the threat is. Armoured Recce has a strong dismounted function that looks very much like what I guess you would think of infantry doing in some cases. Think sitting in a hole and watching stuff while living out of your ruck.
Artillery has a infantry type task in defence of the gun battery. Gunners are trained on a range of small arms and support weapons although their offensive dismounted skills are limited at best.
Neither armour or artillery are capable of holding ground in the way that infantry does. Neither is going to be as proficient in the infantry type tasks as the infantry is going to be and both will use their "infantry" skills as an enabler to accomplish their primary tasks. It would be a rare occasion that you would see artillery or armoured troops "closing with and destroying" the enemy in an offensive operation. In fact, I can't think of a single example in history where this has occured although there no doubt is one or two exceptions that prove the rule.
Bottom line, if you want infantry, go infantry. If you want to be a gunner or a trooper, do so for reasons of what those jobs entail. Also, make sure you understand what the job actually entails. Don't choose infantry because you are really good at Call of Duty or because you've seen Generation Kill (good show) a million times.
The people you are asking advice from are professionals for the most part and while this may blow your mind, you are not the first person to ask questions such as this. The whole "what does each trade do thing" has been covered here before. Here's a post that links to a whole host of topics on being a gunner for example.

http://forums.army.ca/forums/threads/84498.0.html. That maybe took me 1 minute to come up with. Oh, and even better would be look up in this area to the post aptly titled "Comparing the Combat Arms (Inf vs. Engr vs. Armd vs. Arty)". That thread probably answers 95% of your questions. To echo what Jim said, check the attitude.
Best of luck moving forward.
