Methinks "Is it good style to ... ?" 
is not a good question,
as it calls for subjective preferences 
like "is this a beautiful painting?"

You could ask:
"Is it clearer scripting sourcecode for newbees?"
or
"Does this involve less cpu-time?"

Methinks, the clearer code Q is important, sometimes.

The cpu-time consumption is not, as:

- how many times would you want an innerHTML to change per second?

- the difference in fetching a DOM-pointer from a DOM id-array or as an 
object-property [or even as a simple variable] will not matter much imho, 
but you could try to measure that for different browsers, if you like.
