I use Veloplugs in almost all of my wheels now. While Veloplugs are certainly less cheap than rim tape, they’re reusable if you have to change a spoke and withstand higher tyre pressure than the rims themself.

Weight weenies will save around 15g per wheel (32 Veloplugs = 5g, rim tape about 20g per wheel). I actually don’t care about the weight saving, but really like the ease of use of these things and easier mounting of stubborn tyres.
Since Veloplugs come in two sizes (red = 8mm, yellow = 8.5-9.3mm) make sure to choose the right size for your rims.
