where to build phrases?

[itsid]

Hi,just a short question:

What makes more sense,
building the phrases in the plugin with:

PHP Code:

$wsm_p_1 = construct_phrase($vbphrase['sid_wsmhack_date_x_y'], $wsm_date, $wsm_time); 


or building them in the template using

PHP Code:

<phrase 1="$wsm_date" 2="$wsm_time">$vbphrase[sid_wsmhack_date_x_y]</phrase> 


??

Is it just a matter of personal preferation or is there any significant difference
(serverload or something) ?

Thanks
