Should or not is entirely your personal preferance but this one from Frsky is  surely a good choice

Conversion or not depends on you primarily, but these factors are worth contemplating...

1) Do you have enough receivers and crystals ?  Are you able to find new receivers and crystals ?  (BTW, is it 75Mhz or 72Mhz ? ).  2.4Ghz receivers are typically much easier to find, and you do NOT need to hunt down matching crystals etc.

2) In general, the 2.4Ghz stuff has better resilience against interferences.

3) Receivers can be cheap, if you go for like an FrSky conversion.

Just search for Corona or FrSky conversion threads here for the rest.

No need for conversion if you have enough receivers, and your field has no conflict (others in the same band+channel).
