Since the #8 is two tone, any of those will look good aesthetically. The RSST is simpler, but if you want to use e-juices that crack plastic tanks you should stick with AGA-T or AGI. Also, you cannot do U wicks with the RSST. I have the RSST and the AGI. I choose the AGI so I would have the option of using it as a dripper. The wick holes are a little small on the AGI, and the mesh wick hole is close to the center pole, so I don't really want to risk drilling it out. It still puts out enough vapor for me, but not as well as the RSST. Both the AGI and RSST air holes were too small for me and I drilled them out to 1.0mm. I don't have an AGA-T so I don't really have an opinion I can share. Initially I didn't like the way the drip tip wobbled in the RSST, but after using it while driving I found it isn't so bad especially when you hit those bumps in the road.
