Yes, I like the Carlsson, three quick swipes on my new bow and I'm making noise. (maybe if I practiced more I would be making music instead.

Rosin choice is a personal matter, and your own preferences will have to be cultivated as you play and gain more experience. Lots of factors come into play.
You'll find that extremes in humidity can drive you to different types of rosin. When it's very dry (typically winter), a stickier, more moist rosin may be more desirable, when highly humid (summer around here) a drier rosin may be a better choice. At times in my playing life I carried two or three cakes and had the sticky bass bag pocket to prove it.
The SuperSensitive Clarity synthetic Rosin comes in Winter and Summer grades, and Kolstein makes a Duo-Pack that has a half moon of each of two different flavors. If you are in an area where the climate is extreme, those two may be convenient alternatives... and there are many more, as you'll find some who make numbered rosins to indicate the grade.
