I prefer the platform / clipless over double sided pedals for a bunch of reasons... I wear touring shoes which are clipped and very walkable and mtb shoes are much like this albeit a little stiffer.

I usually switch between my touring shoes and mtb shoes as this keeps my shoes fresh and extends their life as they get a chance to air out and also have road shoes that see use about once a week and are dialled in for my spd road pedals.

It is very nice to be able to un-clip and use the flat pedal when being clipped in is not ideal or you want to give your foot a change in position and sometimes you might just want to ride in sandals or regular shoes so the 50/50 pedals offer this option.

In getting started make sure that your pedals are set properly with a lighter release and get clips that allow for inboard and outboard release as some only allow release to the outboard side. Clips can jam occasionally as small debris can cause issues and being able to release to the opposite side can be a good thing.

As you get more comfortable with the pedals you can bring up the tension on the pedal... you do not want them releasing when you are making hard efforts and be prepared to have at least one awkward fall... these will usually happen when you are coming to a stop and forget you are clipped in.
