Are RemoteFunctions still slow when compared with RemoteEvents?

So I’m working on a networking utility, does anyone know if RemoteFunctions still have a delay when compared with RemoteEvents? There was a bug report several years ago which hasn’t been addressed, and some (relatively) recent statements say delay is still an issue (here, here). Does anyone happen to know if this is still the case? If it still is an issue, it isn’t hard to use a wrapper that uses RemoteEvents instead of RemoteFunctions but I don’t want to create too much of a hassle for myself if it isn’t even buggy anymore.
