Lets start with the good stuff...
Best eyeshadow
Yaby Pearl Paints
Gorgeous shimmery colours that are pigmented and easy to work with. I will be reviewing these shortly!
Best mascara
Lorac Visual Effects mascara - lengthens AND thickens! The only drawback is that it does get clumpy with age.

Best coloured liner
Lunasol Geminate liners
Ok this is cheating a little since I got my Geminate liners end of 2008 but because I hadn't really used them as much then I did not realise how awesome they are until this year :) The metallic/subtle glitter in these are so unique and undupeable. They bring a subtle sparkle to the eye without being too obvious unlike glitter liners (eg. Urban Decay's)
Best glitter liner
Too Faced So Smurfy liner in Smurf You (glittery smurf blue)

Yeah I know I just bashed glitter liners above but this is one I really like to use over black liquid liner to jazz it up with more obvious sparkle.
Best concealer
Cle de Peau concealer stick in Beige
Goes on super creamy. Colour matches my skintone once blended right.
Best foundation
Lunasol Water Cream Foundation

This purchase was of course influenced by Fuzkittie. I had been debating this purchase for ages, and was not disappointed as the formula feels divine and glides on beautifully with fingers or sponge. Coverage is excellent since it is a cream but does not feel heavy at all. Best of all, it does not oxidize!
Best tinted moisturizer
Cover Girl Smoothers SPF 15 Tinted Moisture

Finally got to try this (because its not sold in Canada) and was blown away by how well it matched my skintone without oxidizing. Coverage is like a typical tinted moisturizer so that was to be expected. It trumps La Mer and Laura Mercier in that it contains UVA and UVB protection (both LMs have only UVB).
Best blush
Jill Stuart Mix Compact blush in 07 Lovely Tulip
Subtle cool pink perfect for spring.
Best highlighting product
MAC MSF in Refined
Gorgeous peachy glow without shimmer or glitter! Can also be used as blush.
Best drugstore lipgloss
Marcelle Vita Lip Plumping Gloss
Fragrance free, non sticky gloss that gives the illusion of fuller lips without any chemicals to sting your lips. Love it!
Best drugstore lipstick
Joe Fresh cream lipstick in Strawberry
Creamy, pigmented goodness in a tube for CDN$6 - what more could you want?
NOW for the bad...
Here are a few things I regret purchasing - not necessarily for poor product performance but also the price.
1. Guerlain le2 mascara in Bleu Cerise
Too expensive. Even though I hardly used it the formula went clumpy after 3 months. That may sound normal but considering I hardly opened the tube (like 4x in the 3 months) it really sucks!
2. Laura Mercier Tinted Moisturizer

It looks great at first and gives a lovely glow that I got complimented on. However after a few weeks of use I noticed it tends to oxidize and make my face look darker :( For the price I was expecting better...
3. Urban Decay Box of Potions

Already went over this one here - do not recommend! All the products besides the famed UDPP failed to perform for me. Fortunately I was able to return the set.
4. Lunasol Full Glamour Gloss
Pretty to look at but wasn't much different from a regular clear shimmery gloss. Not to mention I paid well above retail, silly me.
