How does being a grad student compare to tenure-track positions at teaching and research universities?

I'm a 3rd year PhD student in CS. Two years ago, if you asked me what I wanted to do after I graduate, I would have said "be a professor" without hesitation. Now, I'm not so sure. The main reason is that I feel like I'm always just barely keeping my head above water. I'm never early on deadlines and I can never spend more than 4 hours working on a single thing. I feel that I never have enough time to be extraordinary at any one thing - I can only maintain being just-good-enough or above-average at many things (I prefer the former). It seems like that is pretty normal for my advisor as well, which has made me second guess my future goals.

However, based on what I've read, there is a big difference between being a professor at a teaching university rather than a research university. So I'm wondering how my current workload as a PhD student compares to those. Is a tenure-track job at a research school very similar to being a grad student? What about a tenure-track job at a teaching school? I'd like to hear some personal experiences on this so that I'm not basing my future decisions off my own predictions.

Currently I have this work load: 1) Continue to progress in research, 2) Teaching a new class (which means all new material), 3) Service work (I'm president of a student org), 4) Prepare for qualifying exams (have to write a survey paper and give an oral defense by next Fall), 5) taking 1 class

This workload seems to be pretty standard. Not everyone is teaching a class, but most are TA's so they still have teaching responsibilities. Not all students are involved in service so they might not have that. 

I'm wondering how similar this workload is to the workload of a tenure-track position at a teaching or a research university?

The workload of a junior faculty member is more than that of a grad student.  This doesn't make it worse, but it does mean for the first 4-6 years, you are working your ass off more than in grad school.  The advantage is that its your work, your field and research interests, and there aren't any exams.
