I've tried sygic, Waze and google navigation.

The best if still Waze. Why?
Traffic info
No other maps can top Waze maps in terms of accuracy and up to date.
Fun
Automated, knows when I go to work and return from work and when sending and fetching my daughter in school. Just brilliantly automated, loads up my route automatically.
Wife can track my journey home and open the gate at the right time. Yeah I do need electric gate but Waze the next best option

Buang masa offline gps. 95 percent of the time when u drive u know the way. What u dono is the traffic condition. Offline gps don't give u traffic condition. Well actually they do but with a price. If u don't want to get data plan than u still living in the zaman batu. Data plan is like your phone extension not only for gps. Can Whatsapp, Skype, hangout, and a million more things that is so worth the price. Imagine someone Whatsapp me I have to wait till u reach home before I can answer. So leceh if no data plan

in KL? hardly. In kuching? hardly too. In kampung? hardly also but i am sure some kampung in deep jungle don't have signal. so i respect that u may have that experience. so go for offline in this case. btw, i have sygic in case that situation happens, and for the last 2 years i only used sygic once.

yeap. for some specific scenarios u might one to get offline gps. i know, i am out of the country very often. and the reason why i bought offline gps was exactly that reason. but since i visit that country so often, i end up buying a local sim card. after that, i find the 100+ RM i spent for offline gps a bit rugi. coz i seldom use.

sure or not, i just typed my fav kopitiam in waze and there it is in foursquare search. i type in sygic, result not found.
