Ive been testing bluetooth modules and with an Bluno nano I was able to get about 40m. Since Bluno nano is a cc2540 ble chip, I was thinking of trying an AT09 but apparently they have the same chip.
Ive read bt goes up to 50-100m max. Ive never found a post about a bt going 100m but they say so 
So I was wondering, would regular 433Mhz be better in terms of range? Im looking for 1-2km range.

Neither blue-tooth or the 433MHz radios will give you that range.
Bluetooth is not designed for long distance communication.
Despite what PaulS said, yes 433MHz radios are very capable of long distance transmission. It's not as simple as the frequency thought, it also depends on the transmission power and antenna. If the radio only produces a few milli-watts the signal won't go very far. If it's a 2Watt radio module with a good antenna you can communicate over 20km. I've used 900MHz radios out to 10miles (16km) and 433MHz radios out to 2miles (6km) for work. You might need a license for higher power radios though.
As an example, here's a low-cost module that claims to be good up to 2km.

And what makes those modules "long distance" is just the antenna or also the circuitry which allows the module to draw more power for a stronger signal?
Both circuit and antenna.
Here's another example product:
It has power output of 100mW and claims 2km range with a simple wire antenna, but up to 20km range with a high-quality directional antenna.
There are quite a few types of '433Mhz' modules, some are short range some long and some just ridiculous.
250km + is easy for some 433Mhz modules (LoRa) even at the minuscule power level of 10mW, and just last week I picked up LoRa from a satellite with a standard £4 RFM98 433Mhz device and a crappy telescopic antenna, range was circa 1,500km.
How far would Bluetooth go ?
