Please do not fixate on what is "better" in programming.

Both ways are standard and so cross-browser compatible.

===

IE allows document.aName where aName is the name of a form or another 
emenent. That is one of MS's serious mistakes, as it is not standard and 
even in IE leads to errors when is html-reserved and used, like the 
document.forms collection. 

===

document.forms["ScrabbleStopWatch"].elements["timeTotal"].value

can be written as 

document.forms.ScrabbleStopWatch.elements.timeTotal.value

which is ok, but

document.forms[3].elements["timeTotal"].value

is a bit dangerous, as the 4th form could later be shifted by you to 
another place, without you realizing the number should be changed.

===

In simple testing I use document.forms[0], to point to the first [and 
only] form, all the time.

===

Using this or this.form is nice:

<form onsubmit='alert(this.name+" to be submitted NOW.")' name='myForm'>
<input type='submit' onclick='alert(this.form.name+" submits shortly.")'>
</form>

especially if you use a common [to more forms or inputs] function:

<input onclick='myFunc(this)'>

===

document.getElementById() can always be used and is quite safe when you 
rmember an id must be unique in html.

===

btw, please sign with a nickname or preferably your own name on this NG, 
talking to and quoting anonimous is cumbersome.
