Swain mats are used in a lot of Judo tournaments and Zebra mars are very good as well. Zebra is used by a lot of Police academys because of their durability. I've used both. they're both excellent products, cost is about the same give or take.

If you have no budget, the Swain mats are excellent. Swain was an Olympic Judo Champion.

Zebra mats look like they are great but I never heard anything good or bad about them.

For Aikido and Jujutsu you will need good quality mats.
