Gold will give you free data from the BATS exchange. Platinum allows for real time quotes and real time scanning.
As far as a nice charting package I didn't mind it when I used it. It's pretty simple and ridiculously easy to use. I've hit freestockcharts before when not on my own computer and it looks identical but it's a bit clunky to me. I think it's paid version is the same cost as GOLD so I would get Gold.
Another nice feature is when I did have TC2000 was I could export TC2000 v7(EOD data only) to Amibroker via their plug in. I'm sure you could even export it to excel somehow easy enough.
It's a very simple software and very customizable as far as the layouts, charts, and especially the ease of using watchlists.
I just moved on to Amibroker myself because for real time its cheaper then tc2000. 99$ I think for platinum and I'm paying a little less for IQFeed data and Amibroker only has a one time fee for a licence.
But if your looking for a EOD charting package and nothing fancy, I'd give TC2000 gold a shot. At 29.99 I don't think its horribly priced and they usually sell it buy 10 months get 2 free, can cancel at any time(just don't get those 2 months free). The platinum is a bit over priced to me.
