If you look at spending, then Colwyn Bay gets far more than Llandudno for capital projects.
*takes deep breath* Porth Eirias, the entire promenade being rebuilt at a cost of £81m*, the new Rugby centre in Eirias Park, a completely revamped Theatr Colwyn, a completely revamped Station Road, a completely revamped Penrhyn Road, a completely revamped Sea View Road, Market Hall project, millions spent on the Townscape Heritage Initiative project, many more millions spent on renovating housing within central Colwyn Bay, acquisition of Government Buildings in Coed Pella road.....and probably a few more than I've missed!
Costs of all the above? Well, I found these two articles:
*"Conwy Council’s coastal defence strategy proposes a programme of phased improvement works to bolster the existing sea wall and maintenance of defences over the next hundred years. The Council has estimated that the construction and long term management of the
Colwyn Bay defence strategy will cost around £81m."

a wider £56 million regeneration of the town."
http://www.itv.com/news/wales/update/2013-05-24/grant-for-historic-pier/If I look at Llandudno in the last 10 years, I can think of the Railway Station (£5m), the Swimming Pool (£6m) and Venue Cymru (£11m). That equates to a total of £22m spent in the last ten years, compared with £137m in Colwyn Bay.
