yes I think so
the arendal is clearly much cheaper and can be expected to have a substantial displacement advantage in the 50-200Hz area
the S300 has 3 tweeters in a v short array vs 1 in a pretty shallow waveguide, if the 300 is like the 150 then that operates like a .5 way with 1 rolling in above 4-5kHz so that's 2 vs 1 in a shallow waveguide. Inclined to give the output advantage to the 300 there but really no idea.
the arendal uses a conventional layout so, if the crossover is well executed (they're not idiots so lets assume it is), should have fairly predictable dispersion
the MK does not and I wouldn't be surprised if it is not well behaved (but no data except my own for the 150 so again a massive unknown)
basically there isn't even enough info to be able to do a meaningful comparison on paper
