Roth's are great and for good reason. Personally, I like them as a tax-free "personal loan device" I don't know all of the details, but I believe that whatever
principal is invested after 5 years (and it's 5 years for each lump sum investment on your 5500 maximum each year) can be withdrawn at any time without penalty or tax. Only the returns are locked away until age 59 1/2.
Or something like that. Basically, after 5 years, if you maxed that year out, you can withdraw $5500 without paying a penalty and without paying taxes on income. 6 years, you can withdraw $11k, 3 years, $16.5k, etc. Again, assuming max annual contributions. I wish these things were beaten into my head when younger--doesn't this sound like a great way to save money (money that earns money) for some time if you have a 5+ year home purchase plan?
There are also arguments against Roth that prefer the untaxed deposit and growth of the traditional IRA

(essentially, your initial $5500 in the Tr IRA is worth more than the $5500 in a Roth, so grows more over the years, with the same protected tax growth.). You need around 6800 to get the 5500 to deposit into the Roth (assuming 20% Tax rate)...so that's $1300 less in capital that could have been growing in that Tr IRA, and add that up each year.
I think ideally you want one of each if you can afford to contribute to each one annually. Especially because of the mechanations of the Tr IRA > Roth IRA conversion ladder scheme to never pay taxes on any of it.

As for me, I don't have a Roth. Not now, anyway. I have one Tr IRA that I opened to roll over all of my old 403B accounts and put all of that into VTSAX, and max contribute each year. I plan to focus on my 403B and the IRA, but I also want to go heavy into the taxable brokerage account. The only way to have actual fuck you money is to grow it in an account that isn't locked away and/or significantly disadvantaged with withdrawals. I know I will open a Roth at some point, primarily to begin that conversion ladder some years from now.
The best option, right now, is the HSA

If you have a high deductible Health Plan, then you can access one of these. If so, you should open one ASAP. Max annual contribution is $3500. It is tax free contribution, tax free growth, and tax free withdrawal--so basically a Roth and IRA combined. Greatest thing ever. Withdrawals are used to pay for qualified out-of-pocket medical expenses (like Co-pays or fancy lumbar chairs, many other things), so best thing is to pay for all of that out of pocket, pile up those receipts in a safe spot over the years, then pay yourself back through your HSA every once in a while. This is a relatively new tool so who knows how long it will be around and if it remains this awesome, but it's not like Congress is suddenly going to take your money away without warning and a plan to move it out without penalty in the event that HSA becomes obsolete (they exist only because of the growth in high-deductible health plans).
As for a financial adviser--first see if your company has an office that offers these services for free, even your 401k Rep can tell you all you need to know. There are good ones out there, but they seem few and far between. Many are not Fiduciaries and so have no incentive to look out for your best interest--only to sell you advice and shitty funds that only serves to line their pockets.
BUT--you should seek advice. I'm just regurgitating information that I learned recently from internet strangers, as well as info that I ignored years ago from smarter friends.
