I Started with splenda but thought that leaves a horrible after taste. I am using canderel now and find it better.
If I have to use any I use Splenda because it's not Aspartame based...I avoid Aspartame like the plague.
Splenda - it's the easiest to use in cooking and in drinks, unlike other sweeteners it doesn't form a skin, and again, it's non-aspartame which is a huge bonus.
The other sweetener I use is from Aldi's yellow-top sweetener (Tesco also sell exactly the same one, in the same container, just a different label and a higher price) which is sucralose based and a very good Splenda substitute.
Anyone heard of "perfect sweet" with 100% natural Xylitol?
