I don't like SPD pedals, so use the old fashioned type with metal cages.
I use MKS Ezy removeable pedals on two of the three family Bromptons. They don't last as long as ordinary pedals, because play eventually occurs when the quick release mechanism wears. But they last longer than the Brompton folding pedal, and it is easier to fit toeclips to them. I generally get between 5,000 and 9,000 kms of use before the play starts to annoy me. For me the shorter service life is worth it on the Brompton as I sometimes need the removeable or folding pedal feature to fit the bike into small spaces.
I have MKS Sylvan pedals (quill, not the Prime model, but similar apart from the pedal cages). About 11,000 kms, no problems so far.
Longest serving pedals so far are Mikashima quill pedals with steel cages (copy of an early Campagnolo model), got those second hand and have done over 45,000 kms on them so far. And pre-SPD Deore XT pedals, with cages rather similar to the Sylvan Prime, about 36,000 kms so far on these.
Both the above, and the Sylvan pedals, have user-serviceable cup and cone bearings. But not that easy to do on tour, as you need something to hold the flats if undoing the cone locknut/cone - I generally use a bench vice or a large and heavy pedal spanner, neither of which are in my touring toolkit.
I have a stock of old but useable metal cage pedals, But if I needed new pedals now for a non-folding bike I would get one of the MKS Sylvan variants, they seem to be very good quality at a reasonable price.
