Depends the brand of padman shorts. If its CA, Ihsan, MB Malik, best to use the Thigh Guards. I haven't used padman shorts in other brands so can't comment on theirs. Padman shorts is good in that no strapping required, that's why I used them last season. But generally thigh guards offer a little more protection. If you play at club range, padman shorts will easily work (dead pitches, lower speed bowlers etc)
I personally prefer to use padman short because the inner cushion for thigh guard becomes a little lighter. I have also noticed in my batting sytle (LH btw), sometime my glove hit the outer thigh guard while playing slog or sweep, so I started using Shortman pad.
