Something unmentioned is that the topsider is much cleaner to use. I used to go through several paper towels and a couple of rags doing my oil changes and with the extraction method, no mess and little fuss...
That said, the topsider from parts shop is plastic and it will deform from the vacuum and hot oil. Since hot oil carries the most dirt along with it, it becomes as most things in life a timing issue and one that's hard to get right. Waiting for 20-30 mins after running at normal temp to begin extracting oil will work most times unless the car got extremely hot, in which case a meltdown will occur. (speaking from experience)
The plastic model also has some funky hose connections which seem prone to wear. When mine has served it useful life, I'm going to replace it with a metal topsider(the original, in a can).
As far as oil, well, that's like picking a religion. I'm Christ... I'm a Castrol guy, I'm going to say go with that!
