Do this two types of charts display the same navigational and topographic information?
is it just the scale that changes?

I see a lot of peoples using ONCs for flying in small and slow ACs, while TPC are available and they have the same scale as a Sectional chart...

More or less. Problem with these for people used to flying with Sectionals, is that the ONC/TPC don't show frequencies, nor all Navaids. The TPC (1:500) and JOG (1:250) are the most commonly used for terrain and geographic nav. The JOG is used by both ground as well as air, the TPC similar to the sectional as mentioned, the ONC (1:1M) similar to a WAC and displaying terrain an cultural relief for recognition up to about FL250, and the JNC and GNC at 1:2M and 1:5M scale respectively, being primarily used for long range, high altitude overwater navigation mostly.

I use JOGs and that's about it for me. Good enough for what I was doing in the A-10 as well as now in helos, since I'm talking with the same map my ground units are.
 
Although these charts ONCs/TPCs/JOG-As are updated, they aren't updated on a regular schedule and as frequently as NOAA sectionals, terminals, and WACs. There may be several years between revisions.
 
As a military dude who has unlimited access to ONCs, TPCs, WACs, etc...I'd rather use a sectional any day of the week.

I would use a sectional too, if they had them.
I don't fly in the US, here we only have ONCs and TPCs, they are both American made, the locals make some ONCs but for some reason they are not North Oriented (so the rest of the charts) and they sell them for like 3 times the price of a NOAA ONC or TPC.

The local AIP has all the informations you need to updated manually the charts.

Airspaces are standard, they look always the same,for flying close to airports, they make Visual approach charts which are really handy and would be nice to have in the US too.
