The Tek is a much nicer instrument. It is like buying an older Mercedes va. a new Hyundai...
And just like that the Tek will likely take more maintenance. Typically the 2400 series scopes need new capacitors in their low voltage power supplies. This is pretty easy to do if you are decent with an iron, an ideally have a desoldering station (cheap Chinese one works fine). I did mine on a 2465. Sometimes there is damage to the boards from leaky caps, which can be easy or hard to cleanup, or repair (damaged traces). Mine had just two caps that had leaked, and cleanup was pretty easy.
The Rigol will give you more on screen displays and calculate things for you, like rise time, frequency, etc.
Personally, I use mainly analog scopes (2465 and a 2232, which is an analog hybrid DSO, whcich will behave as a purely analog scope, or a CRT based DSO). I have frequency counters for that purpose if I need a continuous update, or use the cursors on the scope of I just need a quick read.
So it is really a personal decision, a lot like the old Mercedes vs. Hyundai.
