Depends on what your schedule looks like as well.
I'm a big fan of clen myself, take it once in the morning and you're gtg for the day. Especially if you're talking about the research type clen x alb. Being such a short half life, with alb you need to take it every 4 - 5 hours, pretty unfeasible if you work an 8-5 job and can't really take a container of a controlled substance plus a small measuring syringe with you, if you know what I mean.
Also enjoy the potency that clen provides, and the fact that there are many pathways it can be used; combining it with Eviscerate is just simply amazing and it won't give you nearly close to the sides you would expect taking it normally. It won't be an all around fat loss nor as potent as taking it down the pipe but it will be a lot more mild and focused, which can prove advantageous as well.
They are both good, it's just a matter of choice, really.
