I must confess I was against the fiber caps, until I had it thoroughly explained to me; now it makes sense.
Both metal and fiber work well. There are some reasons to chose either, based upon other construction criteria of any particular filter application.
I use the OCOD only when I can get it cheap. There are "better" filters for the same money (namely the MC in my local Wallyworld). I am not saying the EG is a bad filter; I'm saying there is higher ROI in other products quite often.
I very much like the TG; it's become my goto filter for many applications. As I like longer OCIs, I like the TGs.
I cannot fathom me ever using a FU; not because it's unworthy - far from that. It's just that I doubt I'll ever have cause to run a filter long enough to warrant the cost, even though the FU is one of the best buys for it's feature range in the top tier market.
Anyone who hates on Fram must not be aware that other brands also suffer quality issues. We've seen plenty of MC and Puro and Wix issues recently. I would use any of these brands; none scare me. All brands will occasionally suffer a quality issue; none are immune. To me, the Fram line seems to have hit rock-bottom a few years ago, and is well on it's way to "as goos as" status.
To the best of my knowledge, none of us have market industry data showing true reject or failure rates for any brand. And so, all of this is complete and total supposition on our part. Data speaks, but only when present. The rest is just rhetoric. Because of this, I can only say that my OPINION is that Fram may not be a "best buy", but it certainly isn't junk.
