hi
i am little confuse which one to select for wireless communication between RF 433Mhz module and NRF24L01 ,as i am not using any micro controller so pls suggest me which one will be better
i am using this module to drive motor at receiver end with switch at transmitter

Better in what sense? Cost? Distance? Ability to get through walls? Complexity? Avoidance of other signals? Error reduction? Other?
In any case, you need to tell us, for each module, the manufacturer and the model number. A link to a data sheet would be nice also.
RF24 modules are only tranceivers. They need something, like an Arduino, to feed them messages to transmit and to do something with messages received. The same for bare 433MHz modules unless you are talking about a RF "fob" with buttons. Those need to be "paired" with the receiver (with attached relay). No microcontroller required.

okay
better in sense cost and distance....like RF 433Mhz module needs HT12E/D encoder and decoder will NRF24L01 also needs something extra ...basically i am using it without controller now can you seggest
nRF24L01 and its cousins need a controller to provide SPI bus to send data. (nRF24L01 tells me the integrated circuit that is being used.) Some 433 MHz modules need a controller, some do not. Thank you for specifying "better" in terms of cost and distance, but you still have not provided manufacturer, model number, or other information such as antenna. 433 MHz will get through walls better than 2.4 GHz at the same power. Antenna for 2.4 GHz is generally smaller than the equivalent antenna for 433 MHz. There are tradeoffs to make which cannot be made without more and complete information.

have look at above link the are using NRF24L01 without micro controller
will it be posssible

Those must be plugged into a microcontroller module to work - they don't work stand alone.
Those pictures of Cretiles are interesting. I do not know anything about Rs so I cannot advise on price.
The transmitter shows an antenna already integrated into the PWB module. A controller is not shown but has to be there.
The receiver shows what is probably a controller. It does not show an antenna but it has to be there.
No information was provided about the 433 MHz modules so I cannot advise on a comparison.

okay better in sense cost and distance...
You have an application that requires communication over 10M and there is a device which can do that perfectly well and it costs £1.
There is also a device which can go 10 times further but its twice the price, £2.
Which is the 'better' device ?

A control system of some sort is usually needed at the transmitter side and at the receiver side. A control system that controls these modules.
So, if you had one (or both) kinds of these modules, have you already got plans about how to apply them to your system?

i tried only with RF 433 its working but i want to know is there other advantage (except error cheeking) using NRF24l01

There are many types of 433Mhz module, some with error checking, some are cheap, some are very long range, some easy to drive some not so easy.
Are you assuming we know which 433Mhz module you are wanting to compare with the NRF24 ?

Well the 2Mbaud signal bandwidth isn't to be sneezed at I guess - there isn't much chance of getting that on
the 433MHz ISM band due to its width and allowed modulation types.
As pointed out before there is no such thing as "best", because most components have 5 to 15 important
specifications to compare on, here we have at least these things to consider:
range
power consumption
bandwidth
interference
cost
latency
packet/stream
forward error correction
ease of integration
supply voltage
So asking for "best" without describing your hard requirements and "would be nice if" list isn't meaningful.

Look again at the magnified pics and this quote.
Cretile Receiver and Transmitter works together. As the name suggests Cretile Receiver receives signal wirelessly from Cretile Transmitter. The output port values indicate what is received. Receiver has four outputs.
They are configured as garage door remote tx/rx, 4 digital inputs and 4 digital outputs.
The aerials are on the NRF units.
One NRF Tx/Rx Unit is on top of the pcb, Tx
One NRF Tx/Rx Unit underneath the PCB, Rx, you can see the NRF pin cluster and the onboard controller chip.
Cretile is a modular connection system.
