Both rifle and carbine make fine shooting guns. The longer sight radius of the rifle and longer barrel might make it a bit easier to hit with it at longer distances, and would cut down on the barrel flash and noise that makes it difficult for some people to handle the carbines. The carbines are however easier to handle when hunting thick woods for deer and lots of people enjoy shooting them.
Many of the M44s (with side-folding bayonet) were lightly used before going into storage and can have near mint bores. The M38 carbines probably saw more use, but without the side-bayonet, they are also very appealing to own. The stocks of M38 and M44 carbines seem to have been exhausted both here and in the US (at least fore the moment, there might still be more out there....) whereas the supplies of M91/30 rifles are still pretty good (though I underrstand that it's been a while since the last shipment came to Canada).
If you see a carbine for $200, can inspect it and find that it's in good shape, I think that's a good deal. They were sometimes a bit cheaper when they were readily available, but even then usually had to be mail-ordered, bringing the price up pretty close to $200.
