Circular saw for multimaterial vs steel

Hello,

Im in a need of a circular saw for cutting metal.
Based on my budget and tool availability where I live, I have narrowed down the options to the three in the title:

S185CCSL - Steel cutting circ,
R185CCS & R185CCSX+ multimaterial cutting circs

Aside from cutting metal, I often need to cut wood as well, hower I have a makita circ for that so that is not a dealbraker for the S185CCSL. So the main two questions that I have about these saws are:

1. Do the multimaterial circs have lower performance in cutting metal compared to the steel specific S185CCSL? The specs mostly seem to be the same (1600W motor 3700/3900rpm) based on the specs I would be led to believe that the only difference is form and the provided blade. and that if I put the multimaterial blade on the S185CCSL it would cut wood/whatever else not steel as good as the other two, and vice verca with multimat circs and blades for steel.
2. If the multimat's are still in the race, should I pay 100$ more for the R185CCSX+ over R185CCS? R185CCS has 0-60deg bevel and R185CCSX+ supports tracks (I currently have no plans of buying tracks)

Event with makita circ for wood, all things being equal Id replace it with a single multimaterial circ for ease of storage and use on both metal and wood.
So in the end multimaterial is preferred if it has no drawbacks compared to the steel circ
