dear vs murthy 
here , triphenyl methyl carbocations are more stable , 
reason – the +ve charge of the triphenylmethyl carbocation is distributed over a number of structure the aromaticity of phenyl group allow for many possible resonance structure and thus more potential for delocalisation of +ve charge 
compared to tert butyl carbocation , the +ve charge have no place to run and hide , so, its now a nucleophile magnet , the only thing working in its favour is that its tertiary carbocation and stabilised by hyper conjugation . , which is somewhat weaker than resonance ,

Both phenyl and methyl groups are donors.but phenyl group show conjugation by donating a pair of elector from pi bond and show resonance.such resonance is not seen in case of methyl group as they donate by positive inductive effect.so tri phenyl methyl carbocation is more stable than tert butyl carbocation
