I use myetherwallet because it is compatible with ERC-20 token and most of the ICOs now are ERC-20 so it would be the perfect wallet for me. You have to be careful always though if you visit the website because many sites copy the interface of myetherwallet so that they can phished from others and they have so many victims already. Bookmark this link https://www.myetherwallet.com and as much as possible do not search the site in google because most likely it is a phishing site if you are not careful. A simple dot below a letter will look like the legit site but it is not. You may also received some e-mails informing you to update or upgrade your wallet but do not ever click the link because it will just bring you to a phishing site.
