I was really excited to encounter and catch my first wild Snorlax yesterday. It has 166 HP and 1200 CP.
Then today one hatched from a 10Km egg (199HP/1730CP) and gave me 19 Snorlax candy. The wild one cost me nearly all my ultraballs, most of my razzberries and quite a considerable time.
So what is the point in catching rare Pokémon when I will probably just hatch one sometime anyway ?
I walk to work and back every day – 15-20Km round trip depending on my route, so I am able to hatch a lot of eggs and I don't mind buying a few new incubators every week.

If it is rare, catch it anyways because
What's to lose?
In terms of catching any pokemon rare or not, if you plan to conserve your items, I would avoid catching Pokemon that aren't weak or strong, the "so-so" ones.
Weak pokemon are great because they are usually easy to catch, which means easy stardust and candy, and more pokemon to do lucky eggs. Strong ones might be useful for battling and won't require as much candy and stardust to power up. The one's in the middle are not ideal for any of these usages.
