Yes, nr2 for me.
I use a hose with a soda bottle with the bottom cut off attached to one end.
I put that end in the tank, put the hose out of the wondow, suck on the tube until the water starts to flow .
Gravity will do the rest for me.
I just move the cut off bottle through the gravel and will clean out any debris during the waterchange.
Using buckets is a fast way to start disliking the maintenance, and that's a bad thing in the hobby for you'll be tempted to skip a week.
Waterchanges are fun!

noddy, i found with the bottle that you can fill the bottle with water, and then hold it up in the air so that the water rushes down the hose. when the bottle is nearly empty you put it back in the water so no air gets in the hose and gravity keeps it sucking.
i found that because i was sick of drinking fish water
