Eg. Delivering 10 times using 5 mL pipette or 50 mL burette. Which 1 is more accurate? (ignoring the convenience issues)

You must look at the errors stamped on each bit of apparatus. Multiply the error stamped on the pipette by 10, and compare it with the error stamped on the burette.

For single uses, a pipette is much more accurate than a burette.

In general, it depends on what ur using and how well u are able to manipulate the instruments. Many people find that the burette is easier to handle than a pipette since u only have to pour substances in the burette, but u have to use a pipette filler to fill the pipette at the 25cm3 mark and this takes alot of patience and time.
Personally, in ur situation i would say it would be far more easier to use the burette since all u have to do is fill it up once, whilst you would have to repeat the procedure 10 times using the pipette....do u really have time to accurately do all that, when u can just fill the burette to the zero mark and read on the meniscus??? The burette is better in terms of time consumption and accuracy. Spills from the pipette could give inaccurate readings.....
NB: (Just ensure that u fill the burette higher than the zero mark and spin the tap to release the air bubbles, then u adjust the meniscus to zero)..........

Good luck with your experiment....

I will say burette, despite the fact that you need to work a little harder.
