I don’t have any experience with porting a landline to GV but have been considering porting my cell phone # to GV. After researching it seems the main complaints about GV are:
1. Inability to receive picture text messages (MMS). This wouldn’t apply to a landline obviously.
2. Issues with text messages being delayed. Personally I’ve never had any issues with delayed texts using GV directly though.
3. Possibility of GV service being down.
Also I read some issues about people that ported away from GV and having issues receiving texts from GV users afterwards since the phone number is not actually “removed” from the GV system.
