Purple Original vs Purple Plus

I have decided that I will be purchasing a purple mattress, but I’m torn between the Purple Original and Purple Plus. I tried the Purple Original in store and loved it! But I see there is a plus option online that’s supposedly meant for side sleepers because it’s softer. However, I don’t typically like softer beds. Anybody have any feedback on their experience with the Original and Plus mattresses? Is the Plus worth the extra?

For reference I am a 150lb female who is primarily a side sleeper, but occasionally I sleep on my back.
