In my experiments using different finishes for wood - so far only CA and tung oil - I found that there two finishes produce some noticably different results in feel as well as look.

I find that CA really brightens any wood, and gives it a greater look of depth, as well as makes it look more slick. It also preserves the exact colour of the wood, but usually adds some extra vivacity to it.

I find that tung oil, on the other hand, results in a finish that makes the wood appear flatter or more matte in colour that CA. It can still be brought to a good high gloss, but, seems different from the type of glossiness that CA brings out.

Since tung oil isn't glass clear like CA, it may also give the wood a slight hue. I noticed this quite abit when working with purpleheart. Linked here is a picture of some scales. The completely assembled razor is purpleheart with a tung oil finish, while the unpinned set is purpleheart with CA. There is a noticeable difference in colour between them. The CA finish gives a vivid, almost royal purple colour, while the tung oil has a more maroon hue to it. I also had some yellowheart scales with which I could compare the finish too. Here are two pictures so that you may see for yourself pic1 pic2 (sorry, but didn't take a side by side photo). Although the lighting is slightly different for the two pictures, one may still observe some differences between the two. I for one found that tung oil darkened the overall colour of the wood, while CA keep it bright.

There's also one other thing I've noticed between the two finishes. I find that any wood with a (for lack of more proper word) pearlescent grain is usually best suited with CA, as it pronounces and preserves said quality. It's hard to show without a video, as play of the grain is usually what makes this quality noticeable.

Anyway, those are my thoughts. Just wondering if anyone else who has worked with wood finishes have had similar results. I'm also interested to heart what other kinds of finishes you guys use and their results.
