For the Prius, any of the cheap Wixes will do 5k with no problems. Napa Silver, Proselect, Walmart Super Tech, Microgard, Parts Master, Pro-Tec, etc.
For the VW, Mobil 1 at AAP/Carquest. It's a 15k filter and it's included whenever AAP/CQ runs the Mobil 1 oil change special. Other than Fram, the name-brand filters for this engine are all the same German filter reboxed. Wix, Purolator, Mahle, Mann, Bosch, Hengst, Hastings/Baldiwn, so just shop on price.
Fram-made filters for that VW turbo are made in-house. They pay the patent holder to make it with their own media. The good news is that there is a Fram Ultra for that application; the bad news is that it can cost $30! But if you can get an XG10600 at a good price, buy it! Mobil 1 is also made by Fram, and usually expensive other than when it's on sale at AAP. There's also the OCOD for about $10. And of course, there are some cheap Chinese/Mexican knockoffs (design around the patent)
The only filters for your application with a silicone ADBV are the Mobil 1 and FU/XG.
