Sure, the modern ones are better. But they are also very expensive, and usually only come with the higher end hardware too.
If you are looking for a reasonably priced server today, you are likely to end up with the shitty Java-based KVM.
Dell, HP, Lenovo, and Supermicro all have firmware patches for their current line of servers that replace the java kvm with html5 versions. I assume most other manufacturers are following suit. It would be exceptionally rare to buy a brand new server today with a java based remote console.
