dx3 or futaba 4pk

[reg]

Hi,iv got a KO EX-1 MARS R, i love it and dont really want to get rid,but after nearly mising my finals due to some one not turning there hand set off,i feel the time has come to go 2.4,
iv got it down to the two in the title,
i did own a 3pk and found because the screen was made out of old NHS classes it wasnt very easy to hold,looking at the 4pk it looks like they have moved the screen more into the center of the handset so the ballance looks better,
any advise and which is the best investment
thanks,
Mark
