Comparing the Passport with any other handset in a like-for-like test isn't easy because there's nothing quite like it around. But if a physical keyboard trumps all else for you, then BlackBerry's unassuming 2013 handset is your best bet.
We named it the best QWERTY handset on the market when we reviewed it and while that's been usurped by the Passport they're pretty much in a category all their own these days.
The Q10 is a winner in terms of price – you can get one SIM free for around the £200 mark, its specs can't hold up against the Passport.
The elder BlackBerry boasts impressive connections: 4G, NFC and even microHDMI, but the power isn't there. All the Q10 offers is 16GB of storage, an 8MP rear-facing camera and a 720p 3.1-inch display.
If cost and physical keys are the sole buying decisions you face then grab the Q10, but the Passport surpasses it in every other way.
Apple iPhone 6
The main contender for any top-tier smartphone is the latest iPhone. It might not have the "business credentials" of BlackBerry's offering, but the nearly limitless apps means you can find just about any use for Cupertino's current standard bearer.
Some specifications, on paper, aren't as strong as what the Passport offers: dual-core processor with 1GB of RAM and an 8GB camera around back. But other parts of the handset, namely the choice of 128GB of storage and a 4.7-inch LED-backlit display, are far more appealing.
Apple, as ever, puts a high price on its handsets – so BlackBerry has affordability in the Passport's corner (only just), but I'm not convinced it's enough.
The BlackBerry faithful may argue that the iPhone isn't a business device and that "power professionals" need something more attuned to office needs, but unfortunately, it's irrelevant. Apple has supplanted BlackBerry as the brand to beat in the boardroom.
That being said, the Passport makes a great secondary device to an iPhone – combine the two and you're set for work and play. If you're a millionaire, of course. Or just love having two phones.
Nokia Lumia 930
The colourful Lumia 930 isn't the first phone to associate with a sharp-suited business professional, but it has its benefits. Namely, the Windows Phone 8 operating system will work in beautiful harmony with any Windows PC you happen to be using at the office. Viewing and editing MS Office documents on the phone is a great experience.
Likewise, the 20MP camera that Nokia has fashioned with a PureView sensor and Carl Zeiss lens is very good indeed. There's a range of extra camera apps as well for adding in effects while the tutorials generally just take your photography to another level.
Photography might not be a key feature for business users, but it's an integral part of any smartphone and Nokia has BlackBerry beat in this category. As it does with the 5-inch OLED HD display.
However, there's no way the 2,420mAh battery can compete with the 3,450mAh slab tucked inside the Passport. It's one of BlackBerry's strongest features on this phone and will last for a lot longer than what Nokia can offer. If you want to be editing documents at all hours of the day and night, the Passport will have you sorted power-wise.
