I've used both methods over the years and honestly for the Mk7.5 I'd still drop the sump plug if you can get it up on ramps or axle stands. Extractors are handy if you're doing it on the drive with no access underneath, but you never quite get all the oil out through the dipstick tube, especially with the engine cold - it just doesn't flow as freely. Warming it up first helps a lot if you do go the syphon route.
If you do want an extractor, the Pela ones seem to be the most recommended on here and other VAG forums, just make sure you get a big enough capacity for the EA888.
Only downside with the plug method is faffing about with the sump washer and getting the right torque on it, but you know it's properly empty when you're done.
