But it needs some update that's for sure.
But IMO there's no big differance between several brands.
Basically they all have the same specs, nowadays. The main differance will be the noise they make and the quality. The last one is difficult because the quality can be only determined on their breakdown, which can take some months so not years.
CD-burners is another story.
