I have both the Bosch Compact and the new DLX. I have had the Bosch for a while, and it is an impressive little mixer. Beats the crap out of my old KA (pun intended) which died 6 months ago or so. It looks like a toy and it is very lightweight but the motor is powerful. I have done both high hydration doughs such as ciabattas, as well as fairly dense bagel doughs with good success. Once the dough comes together in a ball, you have to hold the thing on the counter or it will bounce right off but if you can accept that and you don't much care that it looks really cheap, it is a great little mixer for the money.
I am still learning with the DLX but so far I like it. It is easier to make a high hydration dough with this mixer (with the exception of bagels, I tend to make more high hydration doughs in general), and you can just walk away and let it go. It requires a bit more fussing with drier doughs, but you can still make them very successfully. I have done my usual bagel recipe (59% hydration), and I started with the scraper/mixer part then switched to the dough hook as it came together.
ETA - The DLX has done fine with smaller batches (so far, have just done a couple times). My ciabatta recipe uses 500 gm flour and it comes together no problem with the DLX.
