Sorry, but would you really take advice from someone that hasn't seen even off color photos of all the materials you've selected or knows the floor plan of your kitchen. If you post photos of the color and door style of the cabinets and cabinet moldings, a photo or the the name of the coutertop (there are many types and styles of black countertops), the finish and style of the appliances, the flooring you have selected, and the floor plan of your kitchen, maybe you could get sensible advice along of course with a lot of less valuable input. Asking blind strangers to direct you isn't sensible.

However, teak is costlier but has many a variants, please recheck the details if it is First Quality or Burma team. Pricing is usually due to the details. Clients are often duped by initial low-ball offers. Go with one who has better client feedback.
