Just a couple other things to consider before choosing what filter to carry...

The squeeze and mini each cost less than a replacement cartridge for most of the pump type filters, so if you need a new cartridge it is actually cheaper to switch filter types. My experience is the they last longer than the pump cartridges as well.

The squeeze and mini are light enough that if really paranoid about filter failure you could carry two and still be substantially lighter than most of the pump filters.

There are lots of factors to consider, but after using an MSR Sweetwater for years I have been really happy using the Sawyer Squeeze and Mini for the last few years. I find that for most tours a filter isn't really worth carrying, but when they are 2 or 3 ounces carrying one makes sense more of the time.
