Regs are better because they do it full time, and the type of individual they attract is quite often more suited to the infantry life. As well, the battalions draw from across Canada, so that‘s an advantage as well. I made the comment about "hard core" because any unit in Canada has limited training options, so don‘t expect to be doing helicopter assaults and urban combat in mock cities every week. But the battalions ARE professionals at their trade.
That said, there are professionals in the Militia as well, and guys with tons of experience. Being a reservist is what you make it. You can be a bag of ****, or a JTF candidate - it‘s up to you. If you want to be a hard core death tech, than go Reg - that‘s what its for. If you have an interest in the military, want a challange, want a cool job, want get some experience before you do something else or move on, go Reserve.
I would say that for the life of me, I don‘t understand why anyone would join the Reserves in any trade but Infantry, or at least combat arms. I know some support types will flame me for this, but I‘ve never seen a non-infantry Res unit do anything that would provide a challange, create a professional, or instil pride.
However, that said, one of the best guys I ever met in the Militia is a cook with an artillery unit, and he was damn proud of being a cook.
