I jack from the wing tie down points as recommended by Van's. As Bill suggests, side load on the bolt is the main concern. I am only aware of one accident that was caused by a bolt failure with the probably cause being side load. It was a severe example. Low grade bolt, and a steep angle producing a lot of side load.

The jacks I use have a cup and guard that will not allow the bolt head to slip off, even if you tried. I round the bolt head to allow it to rotate freely in the cup.
To avoid side loading, I jack the tail. I tie the tail to the jack and weight the jack so I don't "fly" the tail. If you don't jack the tail, you will have a side load on the bolt.

Other methods like clamping on the gear will not work well if you followed plans with hard lines for brakes. There isn't a very good place to put the clamp on the gear leg. I carry an emergency clamp, sold by Van's, that in a pinch off field, I could make work. I also carry the jack point bolts.

My jacks are the most widely borrowed item at our airfield. They spend more time away from my shop than they do in it. Most of the time they are being used to jack up the many RV's on our field, and the occasional Bonanza etc.... They are plenty heavy duty, purpose built aircraft jacks.

If you use a high quality jack system, nothing is easier, quicker, or, in my opinion, safer. ( not that there is anything wrong with the other suggestions. )

Default Audi Aluminum Jack

Here's another option: An Audi aluminum jack. It weighs 3 lbs. and folds up so it's light and compact enough to carry with you. It's rated at 2,117 lbs. You'll have to make some kind of adapter:

Here's a low cost, easy to use, well make jack point. And then just jack from the wing. They work very well for me.
