I would always drop the oil out, I just think its better letting all the stuff on the bottom drain out for ten minutes. Sucking out would be easier though and probably less messy and so better health and safety wise.
The suction method drains the oil from the bottom of the sump..
You push the tube all the way down the dipstick tube until it hits the sump floor...
My C270CDi holds 6.5 litres of oil.. When I use the Pela oil extractor I remove 6.5 litres of oil.
Some time ago I put a post up on here saying that if I could be bothered i would arrange to have the use of a 4 wheel lift..Then I would use the Pela oil extractor and then remove the sump plu to see what came out (if anything)..
I got a reply post from a forum member who had done just what I had contemplared..
He said NOTHING CAME OUT when he removed the sump plug !!
Also please keep in mind that if you put your car on ramps then your enginge is tilted backwards..Fine if you happen to have a sump drain plug on the rear of the sump... BUT many cars have the drain plug either on the front or half way along. In this case you would NOT be draining all the engine oil !
I should have been a salesman for Pela because everyone that I have demonstrated the pump to has gone out and bought one.
I will NEVER, EVER grovel beneath a car again as long as I live..
