It is going to depend on you, your taste buds and the type of creams, honestly. Bavarian cream takes forever to steep I consider it worth it.
Something like a vanilla cream is going to be different than a sweet cream or a (insert whatever) cream.
I'd suggest (if you have only one cream right now) that you use it in mixes, and you will discover if it works well in many/most, but until you get some variety in your creams you are honestly not going to know if you prefer one over the other. But, if the ideal scenario is to get going, use the cream you have.
Can also check out reviews on the various cream options (I do find a somewhat wide variance, personally) but I sub out creams all the time because I can't handle vanillas for the most part. Also, keep in mind that reviews are from other folks tasetbuds, not yours.
I'd alsor recommend doing a medium sized starter of the cream you have, and same with any others you purchase as creams, many of them, do well with a longer steep time, so you'll have a comparison.
And keep in mind, you can use your testers in mixes! If you like a particular cream that needs steeping, you can add some of the mix to another recipe so it's worth the time to do the tester mixes and etc.
Good luck,
Anna
