Well, what I try and do is this.
Sculpt the nails, and talk to the client (light heartedly) about how I used to bite my own nails - until you learned about how unhygenic it is.
Weigh up wether the client will be ok with you sharing what you know as a pro for their benefit, tell them about the millions of bacteria under the nail plate, how eating hyponychiums and eponychiums is not delicious or nutritious, mention about the side walls of the nail taking ages to repair once chewed away.. how skin grows back quicker and thicker in defense of itself causing the client to have cracked hypo's and epo's, thick over growth that does not look so good etc etc
Or you could just sculpt the nails and talk about some thing else
Sculpting is stronger as it is one entity and has no join or break beneath it due to having to blend a tip on to the natural nail plate.
White tips straight on would leave a bizarre looking enhancement as it would be too far down the nail plate in most cases.
When you sculpt, do it reverse... you can use a cover pink to hide the jagged bitten free edge area, creating the natural length that should be there and then create your tip.
Watch out for any gaps in between the clients nail and the nail form that product could leak through and good luck
