ethernet vs wifi libraries

Hello. Sort of a random question but I'm under the impression that people think the ethernet library has some issues if used heavily and I'm wondering if switching to a wifi shield might solve the issue because it's written better?

Does anyone have any thoughts on this?
Thanks very much.

Well I had a client running on an Ethernet shield on a Mega for almost a year, without any downtime except for power outages.

I’d say that from convenience alone (no network cable etc.) the WiFi is better solution if you have an existing WiFi network. The only issue is feeding the device with the WiFi credentials (which is easily solved by temporarily running an access point and web server to get such configuration data). Look at using an esp8266. You may find that it can even replace the Arduino.
