Text::Table seems handy.

Having two hashes with the same keys, while one of these two hashes (%$keep_best) has at most three elements for each array associated with each one of its keys the other one has a 3-array element associated with each key. So looping through the hash %$best keys and associated array elements is sufficient to blanket elements in the hash %$keep_best as well..values in %$best are completed in %$keep_best (i.e $best{key1}= [1,2,3], $keep_best{key1}=[4,5]).. 
use strict;
use Text::Table;

my $best = {'key1'=>[1,2,3],'key2'=>['f','g','h'],'el1'=>['y','z','z1'
+]};
my $keep_best = {'key1'=>[4,5], 'el1'=>['w','x'],'key2'=>['i','j','k']
+};

my $table = Text::Table->new("key\n---","BEST\n----","KEEP BEST\n-----
+--");
foreach my $key (sort keys %$best){
 $table->add($key,@{$best->{$key}}[$_],@{$keep_best->{$key}}[$_])
                                                        for (0..$#{$be
+st->{$key}});
        }
print $table;
