As Jack said, all noise effects gear equally. The question is what gear can filter it out better?
Some higher end product have better built in filters into their radios. A good example is Trango Broadband. Some radios have higher quality receivers so they can make out the distorted signal better. A good example is Orthogon. Or less likely to be overloaded, because it is spec'd to be able to handle a higher powered signal. But better receive sensitivy, has no benefit against noise. Actually, it just means it can hear more lower volume noise. Unless its argued that the radio generates less internal noise, and one of the reasons it can operate at a lower signel level. When there is noise, there are only two options... How to filter it, or how to avoid it. Avoiding it means antenna choice. Narrow beams, and Thick shielding for increased front to back ratios. How to filter it, means buy a name brand product that integrates good filters (example trango, Alvarion), or use third party add-on filters, to filter it out. There is no one fits all filter. Filters are designed to filter out what you want filtered out. A filter isn't going to help filtering out others signals on the same channels as you are using. If you are in a high noise environment, DON:T get fooled into the trap of deploying at the highest power possible. Thats a game that is never won. All parties on the channel experiencethe same thing, and can all do the same thing to keep increase power to try and win over the interference. The better approach is to pick a product that allows choice of antenna. Then you can select the best antennas, to steer around or avoid the noise. These are one of the benefits that I like to the OEM type stuff (StarOS, Ligo, MT) they allow choice of antenna. (If certified of course :-) Trango's new MM model also allows CPE and AP choice of antenna. (But still in Beta, and they aren't quite ready to ship yet).
