Absolutely; it is something of a shame that Edison is often treated as that era's only example of a great inventor - he was a smart guy for certain, but had many flaws. Not least a ruthless business side that often crossed into the nasty and vindictive, and a single mindedness that meant he wouldn't accept his beliefs could be incorrect (hence sticking to promotion of DC for so long).

Tesla had numerous flaws as well; but he was much more a pure inventor and ultimately uninterested in money. Probably the smarter of the two, and certainly his work was fundamental to modern life (i.e. AC power transmission).

There is probably a lot to take away from learning about both men equally :)
