Which is better for braces?

The Nicefeel. It ships with a dedicated orthodontic tip and 10 pressure settings, so you can dial down the flow around brackets. The Genkent listing does not name a braces tip.

Is the bigger Genkent tank worth the extra $2?

Only if refilling annoys you. The Genkent holds 800 ml versus 600 ml, about a third more water. The Nicefeel still beats it on rating, tips, and price.

Which has better customer ratings?

The Nicefeel, at 4.2 out of 5 from 311 ratings. The Genkent sits at 3.5 out of 5 from 151 ratings.

Do either of these need batteries?

No. Both are corded electric units that plug into an outlet and have no battery to charge.

Which is gentler on sensitive gums?

The Nicefeel, because it lets you set pressure as low as 30 PSI across 10 levels. The Genkent does not publish its pressure range.

There is no reliability data for either, and neither lists a written warranty. The Nicefeel's higher rating is the only durability signal here.
