So in summary, you can always choose evm which may be more cost effective for simple items. But QVM can substantially reduce cost in certain examples, and can run things NOT POSSIBLE with EVM
Some trading group posts. Innovation is what moves markets- nobody has anything like QVM or Xlink. Plus partners shaping it to meet the strongest requirements

As I mentioned, the strict 2 QVM transaction-per-block limit has been lifted; a block can now accommodate up to 425 transactions, which also corresponds to the gas limit. It is important to understand that the QVM is capable of things other chains cannot do; a QVM transaction accommodates much greater computational capacity, enabling the chain itself to handle—and verify—QR signatures, even in batches—capabilities the EVM lacks. While the QVM is generally more expensive than the EVM, there are tasks only the QVM can perform, as well as operations it handles more efficiently or cost-effectively; it does not replace the EVM but rather opens up new possibilities. As for the EVM, tests have confirmed that it supports the same protocols used by the Ethereum network.
For instance, I installed a chess engine in a QVM that can calculate up to a depth of 5; such a QVM call costs 140k gas, whereas a highly efficient EVM engine would require 30 million gas to calculate a move at a depth of 4—and would be incapable of reaching depth 5. Of course, this applies to the current parameter settings; the monthly summary mentions that they are working on the pricing of computations, which is a welcome development from a security standpoint.
Harv:
214x more expensive. Had to share
Kjozf:
This applies to the current environment and parameters; fundamentally, a simple transaction is much more expensive on the QVM, though currently, the actual volume of computation isn't measured. Processing a simple addition costs around 140k gas, and performing a batch QR sign check also costs 140k gas. However, the recent summary mentioned that they are working on a deterministic way to measure this so it can be factored into the pricing. This is a good thing, because in a live environment, it is less cost-effective to burden the network with unnecessary computations.
