If you are referring specifically to Wyndham, deeded ownership is generally ownership at a specific "home" resort (fixed week or points, also known as Club Wyndham Plus/CWP), whereas non-deeded refers to Club Wyndham Access (or CWA). CWA is essentially a club membership. You do not directly own any of the underlying properties in the program; instead the CWA trust owns the deeds.
The discussion on goods/bads of either option come down to (at a minimum):
1) where do you want/need Advance Reservation Priority (ARP) - this is the ability to make a reservation up to 13 months early, vice at 10 months for everyone else. CWP = ARP only at the home resort. CWA = ARP at many resorts, but with limited inventory (for now).
2) Maintenance Fees (MF) - Deeded/CWP, you are subject to the MF of that one resort. Non-deeded/CWA, you get a blended MF of all the underlying properties. CWA MF are currently about $5.56/1000 points. Some deeded resorts are much lower, some much higher.
3) Special assessment (SA) risk. CWP - low probability of a SA if resort is well-run; but there are places that get hit by hurricanes (or is it "typhoon" in the OP's parlance?) which could result in lots of damage to a resort. If you are lucky and your home resort doesn't get hit by a natural disaster, then no problem. In CWA, special assessments are spread across the dozens of properties in the trust. So while you have a higher chance of a resort in the trust getting hit by a SA, the pain will be much less.
Run searches on the following terms (separately!): ARP, deeded, non-deeded, Club Wyndham Access, "points are points," etc. You will see previous threads in which these issues are covered in depth. You will find there are personal preferences as to which is better for a given situation (or you could get both types like some people do).
For me, I prefer the deeded resorts, but that is only because the CWA inventory has not yet hit a critical mass to be useful for ARP everywhere. That, and my deeded properties have lower MF than CWA. I also have newer resorts, so these SHOULD not have as high a chance for a SA (at least that is my thinking, which could be inaccurate).
